skrf.media.rectangularWaveguide.RectangularWaveguide¶

class skrf.media.rectangularWaveguide.RectangularWaveguide(frequency, a, b=None, mode_type='te', m=1, n=0, ep_r=1, mu_r=1, *args, **kwargs)¶

Rectangular Waveguide medium.

Represents a single mode of a homogeneously filled rectangular waveguide of cross-section a x b. The mode is determined by mode-type (te or tm) and mode indecies ( m and n ).
