Hello everyone:
I want to calculate the radar cross section of this ship with ANSYS HFSS,but when I set the plane wave excitation, I can only set the incident wave in a fixed direction.
For example, I set the E0 vector to (0,0,1) ,k vector is (-1,0,0), but I want to directly set the incident wave to theta=90 degree, phi=0~180 degrees to do an angle range scan directly.
How can I set it?
Or I only can slowly set it from phi=0, phi=1...phi=180?
