*:For a certain mode, in a rectangular waveguide, propagation occurs for signals
Information are not sufficient to decide O
Whose frequency is above the cut off frequency
Whose frequency is below the cut off frequency
Depending on the dimensions of the waveguide and dielectric O
The dominant mode of propagation is preferred with rectangular waveguides
* because
we can use air as dielectric O
it is easier than other modes and leads to smallest dimension of waveguide
it is easier than the other modes
it leads to smallest dimension of waveguide
