We demonstrate the physical mechanism of optical Tamm states using the phase properties of the photonic crystals. Based on such mechanism, we propose an efficient way that can precisely produce optical Tamm states at specific frequencies. Moreover, we show that dielectric photonic crystals and single-negative materials can be effectively connected through their reflection phase. Two kinds of on...

Using a fully vectorial three-dimensional numerical approach (generalized field propagator, based on Green’s tensor technique), we investigate the near-field images produced by subwavelength objects buried in a dielectric surface. We study the influence of the object index, size, and depth on the near field. We emphasize the similarity between the near field spawned by an object buried in the s...

In present communication, a new Aurivillius family compound K 2 Bi 4 Ti WO 18 was synthesized, and the impact of swift heavy ion (SHI), Ni +11 irradiation on its surface dielectric properties has been studied in detail. The phase formation this complex oxide, crystallization to B2cb symmetry confirmed by X-ray diffraction. However, post XRD, SEM AFM studies shows amorphization, agreement with t...

In this paper, a magnetically tunable metamaterial is proposed and studied. The metamaterial is based on the combination of ferrite sheets and dielectric rods. The tunable property is originated from the ferromagnetic resonance and electric response of dielectric rods. The retrieved electromagnetic parameters and transmission characteristic showed that by simultaneously inspiring the ferromagne...

Polyoxometalate (POM) hybrid materials have shown potential as spin-coatable, patternable dielectric thin-films and components for lithographic resists. In particular, the octamolybdate cluster has been shown to possess good spin-coating properties and the patterning capabilities of hybrid octamolybdate thin-films were explored using a combination of broadband UV and electron beam lithography (...
