i need fdtd-1D (gauss source) matlab code and with PML. please!!! help me.

## 3D FDTD using FDTD in CST(Computer Simulation Technology)

Hey I am using CST for 3D fdtd simulation. I can do 2D and 1D in C or matlab code but with 3D code becomes complicated hence I want to shift to CST. I understand that CST microwave studio can do the job for me. I just want 5x5x5 m 3D space and take a gaussian source somewhere within this space. I want to (...)

## Simulating Photonic Band Gap crystal and tarnsmition power with FDTD

Hi I am doing research on photonics crystals, using fdtd method and the matlab code I have made it my GUI environment. Do you need to change the structure of the code is updated? In addition, the band gap and spray charts and I can not transfer power to get you please help me (...)

## How can i specify media between 2 curve in MATLAB program

Hello sara67, If you go to my groups website, , and go under resources and you will find some lectures notes. They explain how to place devices on a grid for fdtd and other various numerical methods. Cesar

hi to all. does anyone have a matlab or C++ or fortran code for ADI-fdtd or Leapfrog-ADI-fdtd methods in 2D and 3D? or at least,there is anyone that is familiar with this methods in fdtd? if you have a code,please contact me. my email: shaban_sadeghi@yahoo.com and if you are (...)

hi all. I want to learn particle in cell and fdtd simulation.can enyone help me to learn it? enyone have matlab code? which book i want to study? please help me. thanks

## FDTD problem:coax feeding and transmission line feed model

hi. I have a question in fdtd and antenna feeding. I want to feed my DRA with coaxial cable and transmission line feed model.I wrote a code in matlab. do I have to use from thin-wire modeling,to model inner conductor of coaxial cable? how model outer conductor of coax? I'm confused really!!! please help me...

## near field to far field transformation (FDTD)

hi. I have a basic question in fdtd.I know formula and concepts of Huygens surface and I know formulas of near field to far field transformation (NFTFF) and also I can write matlab codes for this purpose.but I have a simple question. for NFTFF calculations,where I should place Huygens surface?before PML or (...)

hi. I have a question.how can I convert a C code to matlab code?I have a fdtd code to C language and should convert it to matlab. how should do this work? please step by step tell me... thanks...

## problem in simulation of antenna with 3D-FDTD

hi to all. I wrote a 3D-fdtd code in matlab. I have a cylindrical dielectric antenna that surrounded by air(epsr=1).I know maxwell equations and discretized forms of them both in vaccum and dielectric.but I donn't know how import a coaxial feed to my dielectric antenna.this antenna is like of monopole antenna. I placed a (...)

## FDTD code for plasma antenna and error in time-loop

hi to all. why in my 3D fdtd matlab code fields become very big?for example they are from order of 1e20! why my code become divergence? how should set a proper source for my cylindrical dielectric antenna? do I set proper permitivity in programming or should use from averaged permitivity in interface of dielectic antenna-air? this permitivity

## what is error of this 3D FDTD matlab code?

hi friends. I wrote a 3D fdtd matlab code in cartesian coordinates with first order Mur ABC. but I don't konw why my Fields become very big (in order of 1e20!!!). can anyone find it's reason and find my error? I don't konw how import a current source to bottom surface of my antenna. my antenna is dielectric with high negative (...)

## Comparing scattering from cylinder with 2D FDTD and 3D MOM

I have used a 2D fdtd matlab code from Hagness/Taflove to compute the scattered near field from a vertically orientated conducting cylinder. I have then computed an equivalent model from a commercial 3D MOM package and calculated the scattered H filed in the near field at the same location as in the fdtd model(i.e. apart (...)
