The effect of bound states in microwave waveguides on electromagnetic wave propagation

The transmission of a TE microwave field with a frequency ? through G, T, and X waveguide junctions filled with a ferromagnetic is considered. These junctions are known to have bound states with below-cut-off frequencies. A probing microwave radiation with a frequency O applied to the scattering reg...

Description
Summary:The transmission of a TE microwave field with a frequency ? through G, T, and X waveguide junctions filled with a ferromagnetic is considered. These junctions are known to have bound states with below-cut-off frequencies. A probing microwave radiation with a frequency O applied to the scattering region generates magnetic oscillations with frequencies ? + nO (where n = 0, ±1, ±2, ...), which resonantly combine with the bound waveguide states. This effect provides for a new method of studying bound waveguide states and efficiently controlling the transmission of microwave radiation. © 2001 MAIK "Nauka/Interperiodica".
