Electromagnetic Finite-Difference Time-Domain (EmFDTD)
is a basic two-dimensional FDTD code developed at the
School of Electrical Engineering, Sharif University of
Technology.
This code has been written based on the standard
Yee s FDTD algorithm. Applications include propagation,
scattering, and diffraction of electromagnetic waves
in homogeneous and non-homogeneous isotropic media
for in-plane propagating waves. Negative permittivites
or permeabilities as well as dispersion is not included.
Zero, Periodic, and Perfectly Matched Layer boundary
conditions may be selectively applied to the solution
domain.
The program is best suited for study of propagation and
diffraction of electromagnetic waves in Photonic Crystal
structures.
EmFDTD is written in MATLAB language and has been
tested under MATLAB 5.0 and higher versions.
REMOVE removes a TSR. It takes two command line arguments. The first is the name of TSR to be removed (or an * to remove the last one), and the second is a file name which MUST contain the interrupt vectors to be loaded when the TSR is removed.
The code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). The program is currently written so that the incident field always strikes the lower-left corner of the total-field region first. (If you want a different corner, that should be a fairly simple tweak to the code, but for now you ll have to make that tweak yourself.) I have attempted to provide copious comments in the code and hope that a knowledgeable C programmer can quickly map the approach as described in the paper to what is in the program.
The Obfuscated Tiny C Compiler (OTCC) is a very small C compiler. It generate i386 code,include two version.The one generate bin file,the other generate elf file

This mfile inputs an unmodulated sinewave through a simple Rayleigh two path fading channel and shows the output with phase, gain, and attenuation characteristics via animation.
The two C source files in this archive are specific to the TRS-80 Model 4 with
high-resolution graphics board. However, the code which performs Huffman enco-
ding and decoding is of general interest.
