Hi, If i have multilayer of unknown materials stacked, how can i calculate the effective permittivity and permeability of entire slab using Nicolson Ross Weir (NRW) algorithm?
Assume wave is propagating perpendicular to the multilayer surface, and S parameter is calculated using measurement...
This question arise while extracting the metamaterial property from the CST S parameter result.
Depending on the time factor (e^-jwt OR e^+jwt), the S parameters will be time reversed. Please clarify which convention CST adopts.
Q1: Suppose Horn Antenna is used to transmit wave toward a target equipment under test (EUT), then what is the plane of incidence. Since with reference to the Incidence plane, TE and TM is defined. Plane of Incidence is a plane perpendicular to the EUT surface which also contain the incidence...
The reflection coefficient is (S22 or S11) and transmission coefficient is (S21 or S21). I think HFSS will plot S in dB Vs Frequency. From above coefficients you can understand the behavior of the FSS screen. I still you have doubt you can attach the article which you refer.
But the FSS elements resonance frequency, bandwidth will vary with the following. So you have to consider,
-TE/TM polarization ( your S11,21 will be different for TE and TM)
-Incidence angle variation (theta,phi)
-parameters of the FSS elements(like width, length, periodicity,substrate thickness)
Sorry. One more question. Please help to understand TE/TM. Also correct if i am wrong in the following statements.
Assume FSS screen is placed in 'YZ' plane. [polarization angle-Sci;Azimuth incidence angle-phi;elevation inc angle-theta]
(i) 'XZ' is incidence plane. Whether it should be the...
Dear rrumpf! Your posts / replies on this forum on FSS are very useful. Kindly keep helping the FSS community. Still i have basic doubts on FSS, but i wont disturb you continuously.
Thank you rrumpf!
Can you help me to find the number of modes in CST MWS FSS simulation.
Also CST FSS simulation supports TE and TM polarization only. Is it possible to simulate for other angle of polarization (Ex: 60 Degree). Thanks in advance.
Thanks a lot "rrumpf".
Please find the attached FSS array. Its Greek Cross Dipole Aperture Array designed for Band Pass response at 15 GHz. Consider vertical polarized wave strike the FSS at different incidence angles (0 t0 60 degree). For all the above incidence angles, the Electric field is...
For a given dimension of element (patch or aperture type) in Frequency of Frequency Selective (FSS), the resonance frequency (Fr) change with Incidence Angle and polarization.
(Example: Let us take a dipole cross type aperture array. The length of dipole is 1 centimeter. Fr is 15 GHz for...
