Metamaterial loaded waveguide characterization—Some basic studies

Metamaterial loaded waveguide characterization has been carried out to study some basic characteristics like resonant frequency, magnetic polarizabilty, and bandwidth of common type of negative permeability structures viz.: Split-Ring Resonator (SRR) and its variants like Double-slit Resonator (DSR), Square SRR (SSRR) and U-shaped SRR (USRR). The transmission characteristics of metamaterial loaded waveguide to realize stop-band in the normal pass-band of waveguide and pass-band in the normal stop-band of waveguide, being tailorable by changing the geometrical dimensions of SRR has also been included. Such study is expected to be important in the design of microwave and millimetre-wave components using metamaterial loaded waveguide.
