CONTROLLED RADIATION FROM DIELECTRIC SLABS OVER SPOOF SURFACE PLASMON WAVEGUIDES

By O. Quevedo-Teruel

Full Article PDF (778 KB)

Abstract:
The radiation characteristics of dielectric slabs over a transmission waveguide, based on the concept of spoof surface plasmons, are studied in this paper. The proposed structure can be used to control the radiation over a wide band of operation, whilst retaining low Side Lobe Levels (SLLs) and cross-polarization. Leaky modes, broadside radiation and directive beams at fixed angles can all be obtained using various configurations (utilising homogeneous or gradient index dielectric slabs). The proposed antenna design has attractive performance for THz detectors and transmitters.
