Cut-off Wave Number in Microwave Theory Formulas

Cut-off Wave Number depends on the geometry of the waveguide. where a, b are the dimensions of the waveguide and n, m are the mode numbers. And is denoted by K_c. Cut-off Wave Number is usually measured using the Radian per Meter for Propagation Constant. Note that the value of Cut-off Wave Number is always positive.
