Modal parameter k for a waveguide. Write a function kParameter() in MATLAB that returns the k parameter in Eqs.(11.4), for an arbitrary propagating mode in a rectangular waveguide (Fig.11.1). The input to the function consists of waveguide transverse dimensions, a and b, and mode indices, m and n. (kParameter.m on IR)
