antenna the Fourier series would model the effect of the reflections between to the horns.

I have 2 horn antennas facing each other each has a size A & B respectively they operate at a frequency 800MHz to 2.5 GHz. they are a distance D apart. when making gain measurments there is a ringing effect which changes as the horns are moved futher or closer apart. Does anyone know if this...

antenna radiation well as far as i know the solutions are in the form of hankel functions which describe the inward and outward propagating waves. Is it possible that these solutions can be represented by half order integer bessel functions

does anyone know about a paper by a guy called Chu in 1948 describing the radiation q of a electrically small antenna. In it he using Hankel functions to describe the radiation wave of a small antenna. I was wondering if there is another other functions that can describe the same process Lisa

Integral Tom, did you get to talk to your math tutors?

Integral its a definite integral with limits from 0 to L/2 where L is greater than 0. How would you suggest I proceed with solving it using residues Lisa

Integral progress I have actually progressed with it now. The whole point was not to use a computer to solve it but to do it by hand. I am now stuck on this bit any ideas? oh the integral is with respect to dz

I have attachted a word document with the integral on. Does anyone have a suitable suggestion on how to solve this?
