Novel distributed planar negative refractive index material

Research output: Contribution to journalArticleResearchpeer-review


A novel distributed microstrip negative refractive index material (NRI) is presented, which comprises of microstrip line sections loaded with interdigital capacitance and short-circuited stub inductance. This new NRI removes the discrete lumped components and associated fabrication problems of conventional NRI. Simulation and experimental results show that the novel distributed NRI yields larger passbands and more distinct stophands.
