3-D polar radiation pattern plot, arbitrary radiation function . Write a function polar3D() in MATLAB that generates a 3-D polar plot of a given normalized field pattern, f(θ, φ), Eq.(12.18), for a transmitting antenna, like the one in Fig.12.5. The function takes at input three equally-sized matrices: theta (0 ≤ θ ≤ π), phi (0 ≤ φ ≤ 2π), and f, where f is the value of the normalized field pattern in the radiation direction defined by (θ, φ).
