Estruturas de metamateriais compostos volumétricos multicamadas destros/esquerdos são investigadas. A presente estrutura é composta por placas de malha condutora e camadas dielétricas incluindo ressonadores dielétricos. A estrutura composta 2-D do metamaterial destro/canhoto é projetada para a propagação no plano. A análise do modo de propagação foi feita para a estrutura volumétrica sob a condição de contorno periódica ao longo da normal às camadas, bem como para um número finito de tipos de camadas para comparação. As lentes planares com índice de refração negativo foram projetadas e fabricadas para a demonstração. Verifica-se a partir da simulação numérica que o feixe focalizado através da lente plana com grande número de camadas é claramente confirmado tanto na magnitude quanto na distribuição de fase dos campos. Por outro lado, para um pequeno número de camadas, o ponto do feixe não é encontrado na distribuição de magnitude devido ao efeito das descontinuidades entre o ar e a estrutura projetada nas superfícies superior e inferior, mas ainda é encontrado na distribuição de fases. O efeito do número de camadas empilhadas nas características de propagação é discutido comparando os resultados da simulação numérica com a medição.

Abstract: Multilayered volumetric composite right/left handed metamaterial structures are investigated. The present structure is composed of conducting mesh plates and dielectric layers including dielectric resonators. The 2-D composite right/left handed metamaterial structure is designed for the in-plane propagation. Propagation mode analysis was made for the volumetric structure under the periodic boundary condition along the normal to the layers as well as for finite number of layered type for comparison. The negative-refractive-index planar lenses were designed and fabricated for the demonstration. It is found from the numerical simulation that the beam focusing through the planar lens with large number of layers is clearly confirmed in both magnitude and phase distribution of the fields. On the other hand, for small number of layers, the beam spot is not found in the magnitude distribution due to the effect of discontinuities between air and designed structure at the top and bottom surfaces, but is still found in the phase distribution. The effect of number of stacked layers on the propagation characteristics is discussed by comparing the numerical simulation results with the measurement.
