Properties of the angular gap in a one-dimensional photonic band gap structure containing single negative materials

Abstract: Abstract.The linear properties of the angular gap in a one-dimensional photonic band gap structure containing single negative material layers are investigated. This gap forms at oblique incidence due to total internal reflection into the air when the Snell's law breaks down and its lower edge occurs at the frequency where the refractive index of one or both layers of the structure approaches zero. This gap is found to be highly sensitive to the incident angle and the polarization of light, but is not affected … Show more

“…It can be seen that, a narrow gap appears in the vicinity of the magnetic plasma frequency (10 GHz) for TE polarization, while it is absent for TM polarization. This gap can be termed as the angular gap that arises only at oblique incidence other than normal incidence [29]. An SNG gap and a Bragg gap appear in the lower and higher frequency range, respectively, as shown in Fig.…”

“…In particular, the existence of a non-Bragg photonic bandgap, also known as a zeroth-order < n >= 0 gap, has been suggested, detected, and characterized [10][11][12][13][14][15][16]. Specifically, layered systems which combine LHM and ordinary RHM materials were shown to display several remarkable photonic bandgap properties such as longitudinal bulk-like plasmon polariton (PP) gaps [17][18][19][20][21][22], which do not exist in RHM-RHM conventional 1D heterostructures. However, most of the studies on the bulk PP gap have been restricted to isotropic structures, which are relatively difficult to obtain in practice, since most of LHMs are intrinsically anisotropic.…”

“…media, which can be divided into one-dimensional (1D), twodimensional (2-D) [3], and three-dimensional arrangements [4]. In general, because 1D PCLT has photonic band gaps (PBGs) [5], the electromagnetic waves (EWs) cannot propagate in the PBGs under normal conditions [6]. But numerous studies have shown that [7,8], under the condition of introducing appropriate defect layers, a passband at a specific frequency is created in the PBGs, in which EWs can propagate.…”
