Waveguide T-junction as a broadband terahertz variable power splitter

We demonstrate a parallel-plate waveguide (PPWG) T-junction used as a power splitting router. We are able to direct the THz light down either one of the two output channels by integrating a small triangular septum into the waveguide plate. We find good agreement between experiment and simulation in...

Description
Summary:We demonstrate a parallel-plate waveguide (PPWG) T-junction used as a power splitting router. We are able to direct the THz light down either one of the two output channels by integrating a small triangular septum into the waveguide plate. We find good agreement between experiment and simulation in both amplitude and phase. We show that the ratio between waveguide outputs varies exponentially with septum translation offset and that nearly 100% transmission can be achieved. The splitter operates over almost the entire range in which the waveguide is single mode, providing a sensitive and broadband method for THz power splitting.
