Abstract

The paper presents the fundamentals of composite right/left-handed (CRLH)transmission lines and materials,and proposes an accurate circuit model of these structures for the design of practical applications.Three novel applications of CRLH meta-structures,developed at UCLA,are demonstrated:an arbitrary coupling-level backward-wave coupler,a zero th order resonator and a distributed planar negative lens.
