neeed to make dual reflector antenna plz

dual reflector antenna

hi can u make dual reflector antenna ',please

if I design A band pass filter with range of 2 to 6ghz and my center frequency is 4ghz what should be the values given to create a solution setup

how can i find values for sa , sb s0

can you providethe article or research paper please

can you simulate accoustic to sandwich panel ?

Very helpful. Can you explain how to set circularly polarized (RCP or LCP) as an incident wave. In COMSOL there is no direct way to set CP except 1D/2D Axis symmetric space dimension. I tried by setting Background field as (Eb: x=0, y=exp(-j*emw.k0*x), z=j*exp(-j*emw.k0*x)), however the obtained result with this setting and with linear polarization are identical. Because of identical results, I think the setting for circular polarization have some problem. I will greatly appreciate any explanation/suggestion regarding this problem.

same will run for 28Ghz?

Hello, thank you for a well detailed video I would love to make a request.. You are simulating a 2d structure, why is the PBC of ewfd2 for ky and the polarization for px, and if I want to simulate a 3d structure with the light source coming from the z direction, how do I set these two items?

Thank you for this video! I am trying to follow this step. But at minute 11:40, why is the Number of values set as "151"?

Vo2 ka temperature parameter kaise change karenge absorber design..

There is a point that I don't understand, why the material of the patch and the bottom is not gold, but air？

could you list the values you modified to adjust the centre frequency

How to improve the frequency response from 0G to 1.5G. Thank you very much.

Thank you very much

Please help me sir Sir can we make this on free cst studio?

Hello sir, The studio you are using, is it licensed or without license or is it free?

I like your Persian accent . Are you Persian?

Thx

Pls i'm having excitation problem with the port and boundaries Can you help me on that

please expalin more about quadrifilar helical antenna. Best regards

Sir i have designed an pyramidal horn antenna in ANSYS HFSS for frequency range of 12.4-18.2Ghz, i have assigned it wave port and boundaries (perfect E to all faces of horn exept the face of wave port and radiation to radiation box) and gave it driven solution setup and frequency sweep. But sir when i try to validate it, it gives me an error "A wave port must have 'solve inside' objects on one side only. An internal wave port requires a PEC object to be attached to and cover the opposite side before the solution can proceed." Please help me sir I'm trying to solve it for more than 10 days

Thanks

I found your videos very helpful, thank you so much for your efforts, I really appreciate it. But I am facing so many problems in simulation so, may I know where you learned simulation in ansys hfss.

Hi Sir, thanks for this wonderful video👍. I'm working on periodic dielectric gratings and followed all the steps from the video. However, I can't find the correct modes using mode analysis (I know the expected mode profiles). When I added an eigenfrequency step, it successfully found the modes. It seems like the solutions from the two methods don't match. Could this be due to using the wrong periodic condition (I'm using continuity condition)? Do you have any suggestions?

How to measure whether it is 180 degree coupler or not?

This would be nice for the effects of a negative refractive index meta materials that absorbs an infrared beam. A meta material like a catalyst Bismuth ferrite. The refracted field will have a water splitting ultraviolet field, for producing a liquid-phase non equilibrium plasma.

can u share with us your drawing cus ı have an intersect btw helix and strip. I applied same steps but it didn't work

Hello can you tell me what is the configuration of your pc?

please give a video on the design of rectangular patch antenna by the micro_ribbon(feed line) at 2.45GHz frequency (you have to see the reflection coefficient S11 the peak in the frequency 2.45GHZ) with the calculation of the precise dimensions of the patch antenna and how to use the wave guide port in the design of the patch antenna and how to make the ground and the patch by the copper in the HFSS software you want to help me because I find difficulties and thank you for moving forward

How can we plot RCS against frequency?

sir how to convert this same structure into 3D and coat different material on top of it

Thank you for your video Sir. Sir what will be the mode analysis for same ridge waveguide coated with 2D material nanosheet kindly guide

Kazakhstan Hello. Need help developing an invention using new optical fiber “hollow core photonic-substituted vacuum zone or (NANF)” . You can earn a lot of money. The Mickelson-Morley experiment, let's turn it into a school device so that it can be used on a bus or an airplane - this is how Einstein dreamed of testing his theories 100% With the help of the “HYBRID gyroscope” you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,... I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)” where - the light travels 48000 meters in each arm, while it does not exceed the parameters 40/40/40 cm, and the weight is 4 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions. Einstein dreamed of measuring the speed of a train, an airplane - through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. (We are not looking for ether, we will see the work of gravitational quanta) The result is a «theory of everything» in a simple teaching device and a new tape measure for measuring the universe.

Hello, I'm wondering to know if there is any way to calculate the transmitted electric field, which I guess that maybe it would be easier in time domain. I'm trying to calculate the transmission of certain pillar array structure with CST Studio. I have succeeded with COMSOL but I'm able to reproduce the same results, my guess is that the boundary conditions in CST are wrong. I hope you can help me with this.

Hi can you do a tutorial for the similar design a metasurface but in case of polarizer

Why am I getting only straight line in the S-Parameters graph. Can someone help me

Yourformulas or your results are not matching. Something is wrong.

thank you so much what are the parameters of Z0_2, please, position . x,y,z ?

Hello, how can I design the equivalent circuit from any structure of metamaterial absorber? any source?

Hi，If I use this method to impedance match the helical antenna, can such an antenna be processed?

Hello sir，your are doing very well，but I cannot draw colormap after completing the parameter scan. The software reports an error. How to solve this problem?

sir reply to our emails pls

Which year is the HFSS application please

Thank you

Sir ..How do you calculate lambda g1 and lambda g2

Can the same design be done in hfss?

Thank you for the video. Its really very helpful. could you please provide optical fiber grating for mode analysis?

hello sir can you please make a video on multipole decompsition of metamaterials (metasurface) please sir🙏🙏
