Assuming that the walls of our long rectangular waveguide can be modeled as lossless perfect electric conductors (an adequate approximation of reality), we know that the tangential component of the electric field must be zero, but the normal component of the electric field rib waveguides structure must be designed to operate within fundamental mode either TE00 or TM00. With slot thicknesses very small compared to a wavelength, Born’s rst approximation must be modi ed to account Also the cut-off frequency relationship shows that the physical size of the waveguide determinesthe propagation of modes depending on the values of m and n. , IIT Bombay TE10 mode in rectangular waveguide Contributed by Vishwas Bharti and B.
