High-performance combined ring oscillators
Masoud Soltani, Farzan Khatib, Seyyed Javad Seyyed Mahdavi ChabokThe purpose of this paper is to investigate a more robust ring oscillator. Less sensitivity to power supply variations is a target. This is important since low-quality ring…
Water cycle algorithm-based PID controller for AVR
Nikhil PachauriIn a power system, the purpose of automatic voltage regulator (AVR) is the voltage control of synchronous generator. Power system stability and security depends on the AVR.
Analysis of DC bus bar dominant stray parameters based on equivalent calculation models
Shaomin He, Huan Yang, Guangzhuo Li, Sideng Hu, Xiangning HeThis paper aims to analyze the dominant stray parameters of the DC bus bar and focus on weakening the influence of the stray parameters instead of reducing the value of the stray…
Analysis of the structure of different optimization strategies
Alexander Zemliak, Jorge Espinosa-GarciaIn this paper, on the basis of a previously developed approach to circuit optimization, the main element of which is the control vector that changes the form of the basic…
Magnetic shielding of a thin Al/steel/Al composite
Paul Clérico, Xavier Mininger, Laurent Prévond, Thierry Baudin, Anne-Laure HelbertThis paper aims to investigate the efficiency of a laminated composite for shielding applications. The solution has to be efficient not only for the shield against static magnetic…

Theodoros Zygiridis, Stamatis A. Amanatiadis, Theodosios Karamanos, Nikolaos V. KantartzisThe extraordinary properties of graphene render it ideal for diverse contemporary and future applications. Aiming at the investigation of certain aspects commonly overlooked in…
Enhanced method for pulse skin effect calculation of cylindrical conductors
Nebojsa B. Raicevic, Slavoljub R. Aleksic, Ilona Iatcheva, Marinko BarukcicThis paper aims to present a new approach to the numerical solution of skin effect integral equations in cylindrical conductors. An approximate, but very simple and accurate…
Analysis of a wind farm with SCIG integrated into a high power system
Dian Malamov, Ivan Hadzhiev, Vasilina Zlatanova, Snejana Terzieva, Aleksandar GeorgievThe aim of this paper is a steady-state analysis of the basic electrical characteristics of a wind farm with squirrel-cage induction generators (SCIG), integrated into a high…
Quadrupolarisability extraction for planar metamaterial scatterers via far-field response
Theodosios Karamanos, Stamatis A. Amanatiadis, Theodoros Zygiridis, Nikolaos V. KantartzisThe majority of first-principle, homogenisation techniques makes use of the dipole terms of a small particle radiation, and, consequently, the respective dipole polarisabilities…
Design of efficient graphene plasmonic coupling circuits for THz applications
Stamatis A. Amanatiadis, Theodoros Zygiridis, Nikolaos V. KantartzisThe coupling characteristics between adjacent circuits are crucial for their efficient design in terms of electromagnetic compatibility features. Specifically, either the wireless…
Transcranial ultrasonic propagation and enhanced brain imaging exploiting the focusing effect of the skull
Stamatis A. Amanatiadis, Georgios K. Apostolidis, Chrysanthi S. Bekiari, Nikolaos V. KantartzisThe reliable transcranial imaging of brain inner structures for diagnostic purposes is deemed crucial owing to the decisive importance and contribution of the brain in human life…
Analysis of memristor-based differentiating circuit
Stoyan Kirilov, Ivan ZaykovThe purpose of this paper is to propose a detailed analysis of a memristor-based differentiating circuit with buffering amplifier, a capacitor and a memristor.
An adaptive sparse polynomial-chaos technique based on anisotropic indices
Christos Salis, Nikolaos V. Kantartzis, Theodoros ZygiridisThe fabrication of electromagnetic (EM) components may induce randomness in several design parameters. In such cases, an uncertainty assessment is of high importance, as…
Scattering by cracks in a conducting surface
Ralf T. Jacobs, Arnulf KostThe purpose of this study is the formulation of an efficient method to compute and analyse the scattering characteristics of cracks or grooves in a conducting object, where the…
100 years multivibrator-history, circuits and mathematical analysis
Wolfgang MathisThis work is intended to historically commemorate the one hundredth anniversary of the invention of a new type of electronic circuit, referred to in 1919 by Abraham and Bloch as a…
Electro-quasistatic field-simulation of biological cells using balanced domain-decomposition
Sebastian Böhmelt, Nils Kielian, Michael Hagel, Marcus Stiemer, Marvin-Lucas Henkel, Markus ClemensThe purpose of this paper is to present the implementation of a balanced domain decomposition approach for the numerical simulation of large electro-quasistatic (EQS) systems in…
