Can some one send me 2D FDFD code for study purpose?

Hello there, May anyone thankfully recommend a good reference to learn FDFD (finite difference frequency domain) for electromagnetic scattering problems ? I need a reference with matlab code examples (especially for 2D geometries) ! I would also be grateful if any one can send me a basic "1D or 2D FDFD scattering matlab code" in a (...)

scattering parameters and electromagnetic reflection coefficient

Hi everyone, I want to stimulate the reflection coefficient of the electromagnetic absorber. There are scattering parameters in HFSS or CST. Does the S11 represent electromagnetic coefficient? Thank you! Best regards,

scattering from reflector antenna

Hi I want to know the differences between scattering electromagnetic waves from common reflector antenna and the grid one(grid reflector antenna) Is it possible to have the same RCS? thanks

Dear All, Please i am asking about a concept which i do not know if it is exists or not i am solving a problem of electromagnetic scattering from dielectric coated conducting cylinder using mom and the dielectric has epsr>1 and mior>1 and i can not get a proper RCS numerically first i need any available solution about that matter secon

Fortran codes required

Hi, Dear all, Please i want a library of FORTRAN codes for the electromagnetic scattering using method of moments Thanks in advance Ahmed,

Unwanted Spikes In Retrieved Refractive Index

In the process of retrieving Mu and Epsilon from scattering parameter by following D.R Smith's paper electromagnetic parameter retrieval from inhomogeneous metamaterials i got unwanted spikes in real part of refractive index which is as shown 73516.I could not able to understand why i am getting this?Is it due to anti reson

Permeability and Permittivity Extraction From Scattering Parameter

I am trying to design the split ring resonator proposed in electromagnetic parameter retrieval from inhomogeneous metamaterials i.e FIG-2 of the paper in HFSS-11.After simulation i got exact match in magnitude and phase response of S parameter but when i try to extract permittivity and permeability using equation 9 and 10 mentioned in the ab

Phase Response of Scattering Parameter Not Matching

I am trying to design the split ring resonator proposed in electromagnetic parameter retrieval from inhomogeneous metamaterials i.e FIG-2 of the paper in HFSS-11.After simulation though magnitude response of S11 and S21 parameter is getting a exact match but phase response of S11 and S21 is not matching.Can any body suggest me where i

I need book on Method of moment

Please I need a book that treat the solution of electromagnetic wave problem using the method of moment Babinton

Transient electromagnetic scattering from thin wire: MOM Code

Hi, I want to calculate transient current at the center of a thin wire by using MoM in time domain. I implement the formulas detailed in the following book Time Domain electromagnetics pages 52? 55 for calculate the transient current. The source is given by a Gaussian pulse (page 21). My problem is: I find as a result a sinusoidal current

Doubts on these topics - Help needed

Help awaited, kindly help. The problem might be that you have posted in the wrong section (electromagnetic Design and Simulation).

Linear Sampling Method (Electromagnetism)

Hello Everyone, I want to know about Linear Sampling method, especially in Electromagnetism. Could you give me any idea about this method, I am finding the papers of IOP science but couldnt find them 1. The linear sampling method in inverse electromagnetic scattering theory 2. Why linear sampling works Do you have these papers? please send me

someone helps me! i need " electromagnetic scattering by surfaces of arbitrary shape"

if the friend has the ebook"electromagnetic scattering by surfaces of arbitrary shape",can you share it for me.Thanks U!

wall and electromagnetic waves

Hi mauloftin I think it's better you search about scattering form such objects and there are many books about scattering and you can find st in advanced electromagnetics books I hope it'll be helpful

Electromagnetic Scattering pattern of a sphere

Please provide some references on bistatic scattering pattern of a sphere versus aspect angle.

WHat is EM simulation? Which software is more accurate?

Hello me_forouzan! An EM simulation is for "electromagnetic simulation" and it could be defined as a software (tool) for solving any EM problem like, solving antenna fields and behaviour, RF (radio frequency) and MW (micro wave) devices and other scattering/reflecting issues with EM waves! Regarding your 2nd questions; It's depends! If you
