How to extract permitivity and permeability of Metamatarial using CST part1

[@jane3598777]

Sir how to decide the Z distance of background properties?? i saw some people using substrate thickness or substrate length. I don't know which is correct.
thank you!!

[@dilsediltak4ever]

Can you tell me how did you calculate effective thickness of materials for calculating permittivity?

[@sunyas436]

thank you very much

@sun yas
If u get more than 2 max and min than u apply more than number of flouqate mode

Us there any tutorial about the circular split ring resonator

[@minakshimakkar9249]

Could you please help me about how to set waveguide port.which waveguide port we set in case of SRR. How to set polarization and also transmittance vs frequency plot.

@minakshi makkar go to playlist..

[@aniskhawarizmi9311]

how i can get reflection phase of amc?

[@jane3598777]

sir i follow ur step, but in the end i click the start simulation, it show No excitation Sources defined. I dont know why, please help me. thanks

[@Mathswithahmad]

Click on assign port...or email me

[@shereenebrahim7137]

Please help me when i run one rectangler SRR in cst 2018, as your video , this massage appears
No excitation Sources defined
What i can do

[@Mathswithahmad]

@SHEREEN EBRAHIM GO TO THE EXCITATION SOURCE

[@shereenebrahim7137]

Are you referring to ports as waveguide port when you say there is an excitation source? What port may be used if that is this case. @@Mathswithahmad​

How to apply TE and TM polarization?

[@Mathswithahmad]

In which simulations method

[@samiulhabib8095]

Thanks for your response. You applied unit cell in x y direction whereas open in z. My query is what is the polarisation in that case?

[@Mathswithahmad]

Both TE and TM

[@samiulhabib8095]

@@Mathswithahmad Thanks. Could you please suggest me how to find s11 and s21 parameter for a single straight wire, e.g. copper with 1 mm length and frequency in between.1 to 1 THz? Thanks.

I need tutorial for designing of EBG

[@Mathswithahmad]

I will share very soon

[@hamzaasifkhan8421]

I messaged you on FB... please check ur inbox... it’s urgent bro plz

[@Mathswithahmad]

Do u have EBG design paper

[@hamzaasifkhan8421]

Don’t have papers but i already have few designs for my thesis, i need 1,2 more designs
