单负材料平面微腔结构的共振模研究
Study of Resonant Modes of a Planar Microcavity Composed of Single-Negative Materials
摘要
Abstract
The resonant mode characteristics of a planar microcavity composed of single-negative materials (SNG) are studied with the transfer matrix method.It shows that the resonant frequency is mainly determined by the material parameters and structure parameters of the dielectric in cavity.However, the line width (FWHM) is affected by the thickness of SNG reflective layer and it tends to be narrow with thickness increasing.The absorption of SNG decreases the transmittance of resonant mode and reduces the local electric field in the cavity.With the appropriate thickness of SNG, the local electric field in the cavity can reach the maximum.The polarization properties of the resonant modes are also studied.Under certain conditions, the omnidirectional transmission of TM resonant mode can be realized, which is useful for designing an omnidirectional filter.关键词
