Guiding and radiating properties of a metamaterial-based Resonant-Slot coupled cavity chain

Abstract

Application of the Resonant-Slot Coupled Cavity Chain as a Composite Right-handed-Left-handed transmission line (CRLH line) at microwave wavelengths is discussed. Design strategies for both the CRLH guiding structure and the backward-forward scanning leaky-wave antenna are reported. First theoretical valuations point to high power ability of such type of antenna, consisting of slotted waveguide with resonatorbased filling. Applications in experimental plasma physics are intended. Theoretical background, numerical simulations and first experimental results are presented.
