Detailed Description

Cost function for GA-based dipole optimization on a dish antenna.

This function computes a composite cost based on sidelobe level (SLL), beamwidth, and peak direction deviation. It is designed to be minimized by a genetic algorithm.

Parameters

x	Vector of optimization variables [amplitudes, phases].
dish	ParabolicDish object representing the reflector geometry.
dish_analyzer	DishAnalyzer object for evaluating radiation characteristics.
dipoles	Cell array of SimpleDipole objects, used to superimpose additional fields.
Etheta	Baseline θ-component of the electric field (1D array).
Ephi	Baseline φ-component of the electric field (1D array).
phi	Azimuthal angle (scalar) for fixed φ slice analysis [rad].
theta_range	Vector of θ angles at which far-field is evaluated [rad].

Return values

cost	Composite cost value to be minimized by the GA.
