Time Domain Reflection (TDR) - Signal Integrity - with practical examples
มุมมอง 33110 หลายเดือนก่อน
TDR is an important concept in signal integrity of high-speed PCB design and also finding faults in cables. In this video, I briefly explain the concept and make examples that help understand the relation between the impedance of a transmission line and the reflected signals in time domain.

This video shows you how you need two coxial to waveguide launchers, OMT, and a conical horn to make a dual- linearly polarized conical horn.
Simulation of a finite frequency selective surface in Ansys HFSS using FE-BI - part 1
มุมมอง 3.5K2 ปีที่แล้ว
In this video, I show how you can simulate a finite frequency selective surface excited by a horn antenna. To save memory and time, FE-BI hybrid regions are employed to avoid meshing the free space between the antenna and horn. FE-BI hybrid regions are very useful when you want to simulate a large structure such as a finite array with fine details such as subwavelength elements. You can use the...
4-port TRL Calibration of a Quasi-optical Setup
มุมมอง 4182 ปีที่แล้ว
Here, I am using a 8-port Keysight PNA that goes up to 67 GHz, to calibrate a Quasi-optical Setup. I'm using 4 ports of the PNA that are connected to horizontal and vertical ports of the X-band horns. This setup is used to characterize metasurfaces under normal plane wave excitation.

IN YOUR SIMULATION HFSS2, the via should be metal instead of vacuum, is that correct? Thanks for this video
Why not work even when I change the step to 10deg
Thank you ma'am
❤❤❤❤loved your explanation.... Crystal clear ❤❤❤
excellent work
Sir/Madam, The video is very informative. I have a question. How to extract the values of parameters permittivity and permeability and prove that the structure is a unit cell of metamaterial/metasurface?
How do I connect common base amplifier
very nice explanation...
Thank you very much. Very informative.
Finally, the theory of characteristic mode analysis has been dimystified! Thank you so much!
Nice explanation easily understood thank u so much mam❤️
Hi Parinaz, do you have an email address to ask questions?
Thank you very much! Your video taught me how to solve for the phase constant. Could you also teach me how to solve for the attenuation constant of this structure?
What is the typical application for these type of antenna?
By far the best explanation i have ever seen thank you
Very helpful, thank you.
thank you very interesting video
Hello, In my version I have this problem when I try design anything the reference point and diamond cursor is disable
hello Thats the most interesting video of teaching and training I have ever seen. i want to simulate a patch antenna for underwater applications. would you please make a video in this topic?
What is name of the book under the bread board?
Thank you so much 😊
Why insertion loss appear even after calibration , i am having issue . inn my case around 3.7dB insertion loss s21 is appearing.
Hello,Where is part 2?
Hello, Witch is the Band Gap between mode 1 and 2 or 2 and 3?
thanks a lot ur video helped❤❤
Youre too much cute❤❤
10:01 how did you done that
Thanks this video so helpfull 🤩
Nice channel.

Wonderful.
Very informative. Thanks
Dear Madam, I am trying to design a Circularly Polarization reflective metasurface. I want to know , how to Get the accurate circularly polarized reflection parameters when I try to illuminate the unit cell with a circularly polarized excitation wave. I set one Floquet port having two modes, 90 degree out of phase from each other. After simulation, I am able to plot the (FloquetPort1:1,FloquetPort1:1); S(FloquetPort1:2,FloquetPort1:2); S(FloquetPort1:2,FloquetPort1:1); S(FloquetPort1:1,FloquetPort1:2); But they both seem to represent the linear polarizations. How to get the circular polarization, like S(RHCP,LHCP);S(LHCP,LHCP). Is there any formula to calculate it? Thank you.
this paper has all the formulas: ieeexplore.ieee.org/abstract/document/8240664
Dear Prof, I like your lecturers. Please do a series of Phase arrays on HFSS. And calculate the interface and inductance between the array elements.
Can you please be more specific?
@@parinaznaseri Like starting from basic and then go to advance topics in antenna arrays.
nice job!
hello, what is the book you are using?
No book. This is just a circuit that needed to be repaired.
maam can you please upload a tutorial for designing cross dipole antenna on hfss it would be really helpful thanks regards
Are there any particular details you're interested in?
Nice love from Bangladesh
Thanks you ur my savior 🎉🎉🎉
How can I get the laboratory exercise book for electronic devices
Thank you so much 😊😊
Where to buy the book you used here?
