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 in edge of PML?because as distance from
Do you have access to Sullivan's fdtd book? The code for this is in there. I have not ever written the near-to-far field transformation or I would just send you that. If you give me your e-mail address, I could perhaps send you whatevermaterials I have. -Tip
Hi, I am looking for fdtd 3d near to far field transformation code in frequency domain written in C or C++. Please help. Thanks. madd
hi, I've tried to simulate an ebg structure using empire software. I used a plane wave excitation and near field to far field transformation as described by literature 'fdtd Modelling of finite size ebg structure' in empire website. But I receives an error 'ValueError: bad marshal data'. Somebody please help me suggesting what is wrong with my sim
Hello everyone, I'm trying to implement Near to Far field transformation (frequency domain) for my fdtd code in matlab following taflove's books but it doesn't work. I honestly don't understand where I'm doing wrong because I'm following the books step by step. Does anybody have a 3D/2D working code and be so nice to share it? ( cb88(et)
Hi everybody, I am trying to build a program that can be used for solving fdtd problems but I need algorithms to use for the meshing of the geometry and also allgorithm for near to far filed transformation. Regards
Hi, I'm using fdtd for my research and I would be very grateful if you could post or send me any sourcecode for a near to farfield transform. I've already tried to implement Taflove's book's frequency domain transform but I wasn't successful. Please send any code you might have to henlindg(at) Thanks!
please i need help to solve this problem i need to simulat an optical fiber one dimension in fdtd but with i take the materieal to be dispersive and nonlinear and i need to get the electric field at very large distance like 100 km but in simulation i can not simulat this large domain so i need to make some scaling to the material to get the same
Hi everybody, I have written an fdtd code and Have gotten result that I need, but I have a problems with understanding the near to far field transformation implementation in fdtd.I have read taflove book: Computational electrodynamics, the finite difference time domain method, publication of Luebbers on near to far field (...)
can you give me your fdtd code ??
HI I try also to simulate the near field far field transformation with fdtd, for the analysis of a p.a.t.c.h microstip antenna to obtain the radiation pattern. I found many difficulties specially to understand the steps to follow to do this transformation. Could anyone help me ??
Hi everyone, I'm bit a of a beginner with fdtd and i'm looking for some examples of far field implementation (near 2 far transformation). Anyone could help me? I'd appreciate it.
Well, conceptly it can be done by near field and far field transformation. You can see the materials form any classic fdtd books. As for E plane and H plane, you only need to define an angle of radiation pattern you want to caculate such as fai=0 and fai=90
I believe you will need a technique originally developed for antenna measurements: near-field to far-field transformation. I did google search for "near-field to far-field" and fdtd, and got about 10 pages worth of (stuff).
