Novel Offset Complementary Split Ring Resonators on Narrow-wall of Waveguides for HPM Applications

Abstract

A novel offset Metamaterial-based complementary split-ring resonator (CSRR) and its characteristic behavior on the narrow wall of a rectangular waveguide is considered, for the advancement and implementation of high-power microwave (HPM) antennas, operable at L-Band along with other potential frequencies. The architecture improves the properties of traditional slots and split ring resonators (SRRs) mounted on the narrow wall of selected waveguides (radius= 24mm, thickness=3.5mm, chord=0.8., offset=2.7mm)., with their designated frequency regimes. The inter-spacing and offset tuning of the array elements have core effects on mechanical strength, coupling, phase, radiation efficiency, as well negative index properties. The design supports high tunability for adaptation on other architectures, as well as decent phase consistency with THz prospects.
