In this paper, a comprehensive study is presented whereby genetic algorithm optimization (GAO) is used to find the best arrangement of three‐phase high‐voltage transmission line (TL) conductors, that minimizes emitted electric and magnetic fields (EMFs), maximizes power capacity, and avoids corona. Moreover, a financial cost study is conducted in order to show the feasibility of implementing such...
To improve the performances of AlGaN solar‐blind ultraviolet (UV) avalanche photodetectors (APDs), we propose a separate absorption and multiplication (SAM) AlGaN APD with a gradually doped charge layer. The calculation results indicate that the designed APD can significantly increase the maximum gain by almost 40%, and reduce the breakdown voltage by about 9% compared with the conventional AlGaN...
In the field of eddy‐current testing (ECT), most studies on detection probes are primarily based on circular solenoid coils; related research on rectangular spiral coils is rare. In this study, an analytical model of the mutual inductance (MI) between two coplanar rectangular spiral coils was developed in which the two coplanar rectangular spiral coils were placed above a conductive plate. The MI...
This paper proposes frequency regulation of multi microgrid systems. The system under study consists of wind energy, solar energy and energy storage system operating in dissimilar combinations to establish equilibrium among the production and consumer demand. In this proposed work, stability analysis of the concerned model is studied using the Henkel matrix approach of the reduced‐order model. Again,...
A noise circulating voltage‐controlled oscillator (VCO) with an intrinsic injection locking tripler is introduced. Based on the conventional frequency tripling scheme, by integrating the injection transistor pair into the fundamental VCO core, the current of the fundamental VCO core is reused by the injection transistor pair, and the phase noise is reduced due to the noise circulating behavior. The...
In this work, vertically trenched double gate architecture has been investigated, in which the gates are implemented inside vertical oxide trenches. Besides, a silicon‐germanium channel dual‐gate MOSFET with unconventional L‐shaped drain architecture is proposed to improve device performance further. We have shown that the proposed device is the first‐of‐its‐kind device architecture that controls...
In this work, a numerical simulation was carried out to analyze the influence of contact points as well as fibers breakage on the transverse conductivity of unidirectional (UD) carbon fiber reinforced plastics (CFRP). The analysis is based on the calculation of the distribution of the electric scalar potential on a geometry inspired by a cross‐section along the axis of the fibers taken by scanning...
Gas sensors play a crucial role in fields extending from environmental to medical sciences. Modern FET‐based gas sensors have their own set of problems, so, in this work, an ultra‐small and highly sensitive TMDC material‐based gas sensor is proposed. Investigated nanowire‐based gas sensor has a radius and length of 4 nm and 20 nm respectively. Catalytic materials Molybdenum and Palladium are used...
In this article, novel designs of two different types of graphene‐based absorbers of arbitrary geometry have been investigated. The first absorber uses a graphene sheet and an array of metallic patches on silicon substrate for dual‐band absorption without the application of chemical potential. The second absorber is formed of a combination of graphene and metallic patches on the same substrate and...
GSG‐PADs are mostly used structures in Integrated Circuits design. As the operating frequency increases, the coupling effect between the input and output GSG‐PADs is enhanced significantly. This causes signal energy leakage and impacts on the performance of adjacent devices in the system. Beyond microwave frequency, the coupling effect between the input and output of the GSG‐PADs is not only negligible...
