Switchable Substrate Integrated Waveguide

IEEE Microwave and Wireless Components Letters, 2011
A switchable substrate integrated waveguide is presented that can be switched between two different modes of propagation via the biasing of a pin diode switch. To demonstrate the usefulness of the design a single pole single through (SPST) waveguide switch is presented.

Substrate integrated nonradiative dielectric waveguide

IEEE Microwave and Wireless Components Letters, 2004
A new substrate integrated circuits (SICs) fabrication technique is proposed for realizing nonradiative dielectric (NRD) waveguide circuits. This new technique called substrate integrated NRD (SINRD) guide allows the NRD guide be integrated within a dielectric substrate by drilling a pattern of air holes.
