hi,
I want to plot the diffracted field by a PEC wedge. I posted the equation and the main plot and my code's figure in an Image.
and this is my matlab code,but I receive this error:
Warning: Imaginary parts of complex X and/or Y arguments ignored
> In polar (line 192)
In wedgemodal11balanis (line 28)
my code:
what is my mistake ?
why plots are different?

Code:
clc clear all a=pi/4 q=(pi/4:0.01:7*(pi/4)) c=5*pi/12 d=1 f=3*(10^10) y=(3*(10^8))/f p=y w=2*pi*f miu=1 b=(2*pi)/y o=q-a u=c-a e0=(sqrt((pi*1j/(2*b))))*((w*miu)/(pi-a))*((exp(-1j*b*d))/sqrt(d)) inf=10 for m=1:inf e1=1j^(m/2) e2=besselj(m/2,b*p) e3=sin((m/2)*c) e4=sin((m/2)*q) et=(10*log10(e0*e1*e2*e3*e4)) polar(o,et) end
why plots are different?
