Abstract
The designs of cross ellipse-shape metamaterial (ESM) in infrared (IR) wavelength range are presented. They are composed of a tailored gold (Au) layer on silicon (Si) substrate. The characterizations of proposed devices can be (a) manipulated their electromagnetic responses between single-band and dual-band resonances by changing different ratio of macro-axis and minor-axis of ESM. The electromagnetic behavior of dual-band resonance exhibits the resonance with broad bandwidth or narrow bandwidth, while the corresponding free spectral range (FSR) could be controlled from 0.154 μm to 0.607 μm depending on the design of symmetrical or asymmetrical ESM. According to these optical characteristics of cross ESM, we can design ESM-like nanostructures to realize IR filter, polarization switch, band switch, and high-efficiency sensor applications.
