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 from not extending the cyl

help! about results of Allen Taflove's 3D UPML matlab code

hello everyone. I used the Allen taflove's 3D UPML matlab code (the link is ) but the simulation results confused me. Why the Ez look only has positive value and almost no negative value in the cartoon window. In my opinon, it should be alternation by positive and negat

field distribution using 3D FDTD

See Allen taflove's book. The name is Computational Electrodynamics: The Finite-Difference Time-Domain Method. You can find it in www dot 4shared dot com

FDTD newbe - request for fast learning

hi i think u should read allen taflove book this is good book to use and then u should read sullvano book solving by c and if u want any of this book send me and i will upload it to u best regard

How to create triangular lattice?

Nothing matlab specific but there is a section on nonorthogonal unstructured grids in taflove (at least the third edition). Two things to keep in mind though 1) unstructured grids are much slower than rectangular grids (no easy looping) 2) The accuracy of triangular grids in particular is low (high numerical dispersion)

Method for writing 3D UPML in Matlab

CPML is better than UPML because CPML can treats dispersive case. Moreover, the codes are also clearly stated in taflove's book. Please refer to CHAPTER 7

Need a CPML MATLAB code

Hi A couple of months back I uploaded a CPML Fortran code (From taflove's book Thitd edition). Have a look at it. Best Regards Jithesh

FDTD Matlab Near to Far field transformation

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)hw.ac.u

FDTD 2D TE case (Total field formulation, PML)

matlab code attached in taflove's FDTD book by CD. I converted to C code. There is some mistake. if anyone have courage to correct, use it thank for your share ~

Looking for Matlab program of FDTD

taflove's Book delivers matlab files for 1D, 2D and 3D the codes are easy to learn Try to search under FDTD+taflove regards

2D Near to far field transformation in Matlab

Hi, I'm having some problems in implementing a 2D near to far field transformation with matlab. I'm following taflove's book, but I can't get it work! I have few questions: - Do I need both E and H tangential fields, or I can assume a PEC or PMC inside my surface and then use just one of them? - I'm using the fft matlab function to (...)

FDTD Matlab codes for Taflove's book

hi etbiaga can u please provide me taflove book. from where u got that book. plz give me the link.

Berenger's Perfectly Matched Layer

Hi, I have tried to write a matlab code based on TF/SF method 2D FDTD with Berenger's PML. I calculated the fields building a look-up table specified in taflove's book. I faced three problems when I run the simulation; 1) There are a lot of reflections (10% of the magnitude of incident field) in the computation space when there is no scatterer.

Looking for a Matlab FDTD code

Hi Boomerang, here is the matlab code from the book from A. taflove 2nd Ed. 2000 For the first steps with FDTD I suggest the book from D. Sullivan; there you find also some code examples, that can be easily adapted for matlab. Hope this helps. best: Ricy

Help me to implement the UPML ABC for FDTD in Matlab

I have tried to implement the UPML ABC for FDTD in matlab, by following the textbook written by Allen taflove. but I still have trouble to get it going. Does anyone has a sample FDTD code using UPML so that I can have a good look at it? Thanks

FDTD 3D using matlab, its very looong...

Hi all, Here I am attaching the matlab codes for all three scenarios ( 1D , 2 D,3D FDTD ) with PML for 2 cases and a simple radiation ABC for 1 D case.The codes are from the book on FDTD by taflove and Hagness which I bought recently.They are heavily commented. -svarun
