“…This type of filter has a common feature, that is, it contains ultrathin metallic film in addition to the dielectric FPR with smaller number of N . A similar modified structure like Air/M/(L H) N L /2L/(H L) N R /H /Sub has been also reported recently (Shen et al 2009;Chang et al 2009;Liu et al 2009). Here layer 2L acts as a defect, and there are two required conditions for metal M, i.e., its thickness must be much less than the wavelength and its complex refractive index n M = n − jn must satisfy n ≈ n .…”

By using lithium niobate (LiNbO 3 ) as a defect layer, a tunable multilayer narrowband reflection-and-transmission filter containing an ultrathin metallic film is proposed. Due to the voltage dependence of the refractive index for LiNbO 3 , tunable optical filtering properties have been theoretically investigated based on the calculated wavelengthdependent reflectance and transmittance. The dependences of peak wavelength on the applied voltage and the angle of incidence are numerically illustrated. The results reveal that in addition to working as a tunable filter, it can also be expected to act as a refractometric optical sensor.

“…In the periodic structure composed of single-negative materials, there exists a new gap (zero-φ gap) resulting from a zero total phase [5,16,[19][20][21]. It was shown that the heterostructures constituted by ENG and MNG materials can possess tunneling modes inside the forbidden gap, which are independent of incident angles and polarizations and have zero phase delay [22,23]. In the recent years, the nonlinear responses of the periodic structure containing DNG or SNG materials were theoretically studied [24][25][26][27][28][29].…”

The nonlinear responses of a one-dimensional heterostructure containing two kinds of single-negative materials with an air gap are investigated. It is shown that the frequency of zero-phase gap bistable heterostructure can be tuned simply by adjusting the width of air gap. On the other hand, the optical bistability is achieved at very low values of input intensity due to the enhancement of Kerr nonlinearity near the frequency of the defect mode. It is shown that transmission of the structure is relatively insensitive to incident angle and losses.

Abstract-The objective of this work is to analyze electronic transport phenomena, due to ionized impurity scattering in δ-MIGFET (Delta-Multiple Independent Gate Field Effect Transistor). In this work, we report theoretical results for electronic transport in a delta-MIGFET using the device electronic structure and analytical expression of mobility and conductivity. The results show that the analytical mobility and conductivity are a good way to analyze transport in this device. We find the relative mobility as a linear and increasing function in different modes; also, we find transconductance as an almost flat function in all the evaluated interval. Finally, we analyze the differential capacitance and resistivity, and we report regions where this device is operating in digital and analogue mode. These regions are delimited in terms of intrinsic and extrinsic parameters of this device in symmetrical mode.
