Basic routines for Spherical Wave modelling in the Far-Field

Main functions:

q = myVc_swe(F,J,varargin)

Vector field Series expansion in terms of Vector spherical harmonics Inputs

• F: Vector Field to expand. (Struct with fields theta and phi)
• J: Number of harmonics, J = 2N(N+2)
• varargin: theta, phi (rad) Outputs
• q: Vector with odd (s=1) and even (s=2) expansion coefficients in alternate fashion

F = myVc_sws(q,varargin)

Vectorial farfield reconstruction from a Spherical wave expansion Synthesis, given the coefficients of a series expansion in spherical harmonics Inputs

• q: Vector of coefficients
• varargin: theta, phi Outputs:
• Reconstructed field. (Struct with fields theta and phi)
