Uniform Circular/Cylindrica​l waveguide field plotter

Plots transverse fields of any uniform cylindrical waveguide mode

Main plotting function is 'circular_wg_plot.m'.

Variables 'm_max' and 'n_max' sets the maximum azimuthal and radial orders for generating the mode list. This list is then sorted according to cutoff wavelenghts. Variable 'mode_nr' chooses the mode from the sorted list for plotting (the list is printed in console).

Examples:

TE11 mode:

TM11 mode:

With m_max = 8 and n_max = 6, mode list follows the same numbering (degenarate modes may have the numbering swapped) as seen in this popular sheet often found in literature:

Code uses function zerobess() written by Jonas Lundgren for calculating the roots of Bessel functions of first kind.

Code is tested only in MATLAB 2015a
