Abstract
Nonreciprocal Composite Right/Left Handed (CRLH) metamaterials are reviewed showing combined
eigen-mode and transmission–line approach along with a formula for the phase nonreciprocity. Pseudotraveling
wave resonators based on the nonreciprocal CRLH metamaterials and their unique
characteristics are also presented. In addition, enhancement of nonreciprocity using coplanar
waveguide-based metamaterials are proposed and demonstrated in the experiment.
