In this paper we have designed and optically simulated a cheaper and flexible ultra-thin film GaAs solar cell having active layer thickness of ∼0.5 micron, even less than the GaAs cell with highest conversion efficiency (∼3 micron). The structure consists of an anti-reflection coating (ARC), n-type and p-type GaAs active layers. A combination of back reflecting pyramidal structure of Aluminium-Titanium alloy (AlTi) and a photonic crystal (Ge rods in SiO2) is used in order to increase the optical path length of the incident light and reflect back the desired portion of the incident spectrum back to the active region to enhance absorption. The cell structure is simulated using FDTD algorithm. Analysis of optical characteristics is done and found that the efficiency has crossed the Shockley Queisser (SQ) limit by ∼6%. Reduction in the thickness of active layer and the use of Aluminium-Titanium as textured back contact has made the cell cost effective.

A periodic frequency selective surface (FSS) having triple frequency band reject behaviour has been proposed with a square and two dodecagon shaped element. These three elements of the FSS unit cell are embedded on the FR-4 substrate, which acts as a triple band reject filter on the frequency band 1.8 GHz, 2.5 GHz and 5.5GHz to avoid the leakage of GSM, WiMax and WLAN signal outside the building. The FR-4 substrate has the loss tangent of 0.02 and relative permittivity of 4.4 with the dimension of 0.12 λ × 0.12 λ that told us the compactness of the structure. The designed FSS has verified by its simulated results and realized in CST Microwave studio in frequency domain solver based on FDTD method as well as also verified in the ANSYS HFSS software. The proposed FSS exhibits more than 91% band reject characteristics for the frequency band 1.8 GHz, 2.5 GHz and 5.5GHz. The FSS unit-cell has symmetrical structure to allow the stable behaviour for both TE and TM mode with the variation of incident angles from 0°–60°. Moreover, the stable resonant frequency response and polarization independence has verified by all its simulated results.

In present work, secure communication scheme for digital images based on discrete time unknown input observer (UIO) design blended with discrete time chaotic encryption is presented. Chaotic signals are pseudo random signals with no periodicity over infinite length. However, the series can be generated with the precise knowledge of the few parameters like system parameters and initial conditions of the chaotic system. With the given nature of pseudo-randomness and extreme sensitivity to parameters, chaotic sequences are ideal for encryption. In literature, these chaotic sequences are generally generated using continuous time chaotic systems. Since image data to be transmitted is in digital form and encryption algorithms are also executed on digital devices, so it is proposed to use discrete time chaotic communication scheme. Further, its effectiveness for encryption of digital images is also analyzed. To further enhance the security encrypted data is embedded in the dynamics of discrete time chaotic transmitter system. To recover the message at the receiver, design of discrete time UIO along with a procedure to recover unknown message signal using estimated states is given. Existence conditions for the UIO are analytically derived in terms of LMIs. Solution of these LMIs gives the observer design matrices. Robustness of UIO based chaotic communication scheme against attacks is analyzed by studying return maps of the transmitted signal. It is reported that security of chaotic communication scheme can be compromised by studying the return maps of the transmitted signal. To validate the proposed approach results of simulation and security analysis are presented.

Bandwidth enhancement of a rectangular monopole UWB antenna using M-shaped strip with triple band notched characteristic is presented. Antenna consists of an exciting rectangular patch with two C-shaped and one inverted U-shaped slots along with defected ground plane which is coupled with M shaped strip. By inserting slots to the rectangular patch, three notched frequency bands are achieved. A conceptual modal, which is based on the simulated impedance of the proposed rectangular patch antenna, is also made to investigate the triple band notched characteristics. The simulated impedance bandwidth of antenna defined by VSWR < 2 is 8.80 GHz ranging from 3.35 GHz to 12.15 GHz with triple band notches first at WiMAX (3.53 – 3.98 GHz), second at WLAN (5.16 – 5.80 GHz) and third at ITU-band (7.82 – 9.08GHz).

This paper reviews the various existing direct optical network unit (ONU) interconnection schemes which provide direct communication among peers resided locally. Direct inter-ONU communication provides the opportunity to reduce substantial latency among two communicating ONUs. In reviewed schemes, ONU data is transmitted directly to the destined ONUs by avoiding transmission to the OLT, thus OLT complex re-routing, rescheduling and re-modulation is avoided. Direct ONU intercommunication does not impose any extra burden on upstream and downstream bandwidth therefore efficient bandwidth utilization is also increased. Reviewed schemes also utilize the OLT and ONU transceivers (TRxs) efficiently and reduces the energy consumption and OPEX.

Order reduction of large scale single-input single-output (SISO) linear time invariant (LTI) systems using stochastic fractal search (SFS) algorithm has been presented. Stochastic Fractal Search (SFS) is a metahuristic algorithm growth using the concept of fractal. SFS employs the diffusion property observed in random fractals to explore the search space. Stochastic rules like; Gaussian walks are used to change the iteration process to generate random fractals. Here, for order reduction of LTI system, SFS Algorithm is used. Integral square error (ISE) in between the transient responses of original higher order and reduced order system has been taken as an objective function, which has been minimized. The step and frequency responses of both low and high order systems have also been compared along with the transient response's parameters. A comparative study of ISE with the other existing techniques in the literature has also been given in the tabular form to show the superiority of the algorithm.
