A rectangular aperture antenna is excited by a waveguide with a TE10 wavemode. The aperture lies in the xy plane, and the aperture field is assumed ? ?(?, ?) = ?y?0 cos (?? ? ), where E0 is constant (V/m). Let us also assume that a, b >> . a. Calculate the direction of the electric field strength vector within the main lobe area and determine the polarization state (linear, elliptic, circular). Describe the polarization and discuss how it aligns with your initial assumption
