line source excitation in RCS

hi everyone,

I am working on rcs calculation for 2D object with MoM with an incident plane wave as a source(excitation). But i need to change source with the line source but I dont know how? thanks in advance.

"not revision control system. It stands for Radar Cross Section. numerical electromagnetic problem is that I have mentioned."

try this

source_pnt=[0,0] %location of line source n=1:observation_pnt %number of cells in 2D structure R=sqrt((observation_pnt(n,1)-source_pnt(1))^2 + (observation_pnt(n,2)-sourec_pnt(2))^2); E_inc_line(n)=-(1/4)*(2*pi*frequency)*permeability0*besselh(0,2,k_constant0*R);
