In this paper, we address resonant leaky-mode reflectors made with a periodic silicon layer on an insulating substrate. Our objective is to explain the physical basis for their operation and to quantify the bandwidth provided by a single resonant layer by illustrative examples for both TE and TM polarized incident light. We find that the number of participating leaky modes and their excitation ...

This paper presents equivalent circuit modeling of active planar reflectors which can be used for the detailed analysis and characterization of reflector performance in terms of lumped components. Equivalent circuit representation has been proposed for PIN diodes and liquid crystal based active planar reflectors designed within X-band frequency range. A very close agreement has been demonstrate...

The analysis of scattering characteristics reference reflectors buried in the ground is carried out. Bistatic diagrams metal spheres with a small ratio length irradiating field and radius sphere are given. dependences EPR disk on its depth immersion sand calculated. results georadara study described. algorithm aperture synthesis Hilbert transform formation radar image local object near irradiat...

In this paper, we present the design and fabrication of hybrid dielectric-metallic back surface reflectors, for applications in thin film amorphous silicon solar cells. Standard multilayer distributed Bragg reflectors, require a large number of layers in order to achieve high reflectance characteristics. As it turns out, the addition of a metallic layer, to the base of such a multilayer mirror,...

Multilayer optical reflectors constructed from 'stacks' of alternating layers of high and low refractive index dielectric materials are present in many animals. For example, stacks of guanine crystals with cytoplasm gaps occur within the skin and scales of fish, and stacks of protein platelets with cytoplasm gaps occur within the iridophores of cephalopods. Common to all these animal multilayer...

In nowadays intergrated circuit design, the diffraction limit has restricted the downscaling of the conventional electronic components. Surface Plasmon Polaritons (SPPs) are quantized charge density oscillations that occur at the interface between metal and dielectric materials when photons couple to the free electron gas of the metal. The extraordinary properties of SPPs can be utilized for su...
