Detailed Description

Computes the far-field components radiated by a pyramidal horn antenna.

This function models the electromagnetic far-field radiated by a rectangular pyramidal horn using physical optics and Fresnel integrals. It calculates the spherical electric and magnetic field components based on geometry and frequency.

Parameters

eta	Intrinsic impedance of the medium [Ohm]
a	Width of waveguide aperture in x [m]
b	Height of waveguide aperture in y [m]
a1	Aperture width at horn opening [m]
b1	Aperture height at horn opening [m]
rho1	Distance from waveguide aperture to horn opening in y-z plane [m]
rho2	Distance from waveguide aperture to horn opening in x-z plane [m]
freq	Frequency of operation [Hz]
E0	Field amplitude scaling factor [V/m]
r	Observation distance(s) [m]
theta	Elevation angle(s) [rad]
phi	Azimuthal angle(s) [rad]

Return values

Er	Radial electric field (zero)
Etheta	Theta-polarized electric field [V/m]
Ephi	Phi-polarized electric field [V/m]
Hr	Radial magnetic field (zero)
Htheta	Theta-polarized magnetic field [A/m]
Hphi	Phi-polarized magnetic field [A/m]
