Diffraction by a perfectly conducting cylinder using UTD???! Hi all, Does anybody know the equations needed to predict the diffraction of electromagnetic waves by a perfectly conducting cylinder using UTD? I want to use these equations in ray tracing. I tried to read some papers and a book "Introduction to the Uniform Geometrical Theory of Diffraction" .. They were so complicated and I didn't understand anything actually (I'm a computer science student :) ). Thanks in advance.
