RectangularWaveguide initializer
Parameters
----------
frequency : class:`~skrf.frequency.Frequency` object
frequency band for this media
a : number
width of waveguide, in meters.
b : number
height of waveguide, in meters. If `None` defaults to a/2
mode_type : ['te','tm']
mode type, transverse electric (te) or transverse magnetic
(tm) to-z. where z is direction of propagation
m : int
mode index in 'a'-direction
n : int
mode index in 'b'-direction
ep_r : number, array-like,
filling material's relative permativity
mu_r : number, array-like
filling material's relative permeability
*args,**kwargs : arguments, keywrod arguments
passed to :class:`~skrf.media.media.Media`'s constructor
(:func:`~skrf.media.media.Media.__init__`
Examples
------------
Most common usage is standard aspect ratio (2:1) dominant
mode, TE10 mode of wr10 waveguide can be constructed by
>>> freq = rf.Frequency(75,110,101,'ghz')
>>> rf.RectangularWaveguide(freq, 100*mil)
