The EM Wave MATLAB Library consists of a collection of MATLAB programs related to electromagnetic wave scattering with special emphasis on wave scattering by random rough surfaces and discrete random media. This web site will be updated regularly, as new programs become available.

Detailed descriptions of the theories and formulations behind these codes can be found in the three-volume book Scattering of Electromagnetic Waves published by John Wiley & Sons:

• Volume I: Theories and Applications (2000) by L. Tsang, J.A. Kong, and K.H. Ding

• Volume II: Numerical Simulations (2001) by L. Tsang, J.A. Kong, K.H. Ding, and C.O. Ao

• Volume III: Advanced Topics (2001) by L. Tsang and J.A. Kong
