This paper presents a structure of half-width two-dimensional periodical perforated microstrip on uniform ground. Perfect magnetic conductor (PMC) boundary and perfect electric conductor (PEC) boundary are applied at the edge of the half-width, respectively. The dispersion curves show that different left-handed and right-handed modes are excited with the perforated periodic structure when PEC boundary...
This paper presents the modal characterizations of two-dimensional periodical perforated microstrip on uniform ground. The numerical method based on multi-port ABCD matrix is used to extract the complex propagation constants of the multi-port periodic microstrip structures. The extracted result shows that right-handed modes which have positive sloping phase constant, and left-handed modes which have...
