How can I perform a specific type of integration in POSTFEKO
Hello, My problem statement is that I have to input an f(t) at one end of the waveguide and obtain an integrated poynting power density that looks like where E(w,z) = F(w)* J(z)*g(|r-r'|); and g(|r-r'|) is the green's function, J(z) is the aperture current and F(w) is the frequency spectrum of f(t). Can this be possible in…
