Surface states in photonic crystals

Abstract

Abstract. Among many unusual and interesting physical properties of photonic crystals (PhC), in recent years, the propagation of surface electromagnetic waves along dielectric PhC boundaries have attracted considerable attention, also in connection to their possible applications. Such surfaces states, produced with the help of specialized defects on PhC boundaries, similarly to surfaces plasmons, are localized surfaces waves and, as such, can be used in various sensing applications. In this contribution, we present our recent studies on numerical modelling of surface states (SS) for all three cases of PhC dimensionality. Simulations of these states were carried out by the use of plane wave expansion (PWE) method via the MIT MPB package.

Propagation of electrostatic surface wave along the dust void boundary

“…In this case, the density distribution of electrons in dusty plasma region B will be same as the equation (7). However, since it is considered that DA wave is present as the volume wave in the region B, therefore, ions are treated as isothermal having the following density distribution…”

“…The study of surface wave propagation in plasma has been carried out inhomogeneous/inhomogeneous and magnetized/unmagnetized plasmas having ramification in several application areas. For example, generation of large area plasmas for nanoscale material synthesis and processing for use in electronics industries [4]; for production of high density flat plasma discharge and high-frequency (1 MHz-10 GHz) cylindrical discharge plasma column for making of plasma antennas [5]; making of microwave plasma torch at atmospheric pressure [6]; surface EM wave propagation along dielectric photonic crystal boundaries for various sensing applications [7] and surface plasmon resonance technique for medical use [8] can be mentioned. In microwave discharge sustained by surface wave propagation, Ivanova et al [9] have used the radio physics method to study the behavior of plasma.…”

Fotonik Kristallerde Yüzey Kipleri Özelliklerini Kullanarak Bağlaştırıcı, Demet Bölücü Ve Algılayıcı Tasarımları

“…Bu bağlamda oluklu yüzeydeki bir metalik film ile yüzey düzeni değiştirilmiş bir fotonik kristalin her ikisi de benzer özellik taşımaktadır. Her iki yüzeyde de yüzey üzerinde yerelleşmiş elektromanyetik kipler desteklenmektedir [5]. Bu bulgunun sonrasında fotonik kristal dalga kılavuzunun yüzey düzeni değiştirilmiş yapılardaki ışıma etkisi üzerine teorik ve deneysel olarak çok sayıda çalışma gerçekleştirilmiştir.…”
