This research presents the design, simulation, and characterization of novel resonator structures based on the principles of coupling electric fields using periodic metamaterial-inspired configurations using COMSOL Multiphysics RF module. The resonators are meticulously crafted to ... En savoir plus
THz is an emerging technology which can be strongly utilized in the field of spectroscopy, communication, biomedical, non-destructive evaluation (NDE), food industry and many more fields [1-2]. It covers the frequency range from 0.1-10 THz [2]. At THz regime, to achieve the high output ... En savoir plus
High-power THz TWTs of frequencies between 0.1THz to 0.3THz are being investigated for their use as amplifiers in ultra-broadband wireless communication systems, because of their high gain, high efficiency, wide bandwidth and high linearity. They have many other new emerging applications ... En savoir plus
The concept of invisibility in general has been imagined in science-fiction in fascinating ways such as invisible aircrafts, invisible cars, cape of invisibility etc. which has inspired a lot of interest in the field. The first crude attempt at achieving invisibility was inspired from ... En savoir plus
The high-power microwave sources generate waves with the output mode of TM01 mode which has null at the boresight upon radiation. The output mode of the source is transformed to some other mode having a maximum field pattern at the boresight such as TE11 mode. In this work, a compact, ... En savoir plus
The axion is an excellent cold dark matter (CDM) candidate, originally proposed to solve the strong CP problem in strong interactions. A novel method to detect galactic axions is by using their conversion to electromagnetic waves from boundaries between materials of different dielectric ... En savoir plus
Exciting plasma in inductive mode is attractive due to the high electron density and the absence of ion interaction with the reactor walls. However, any real system excites plasma at low power in capacitive mode with strong interaction with the walls. The transition from one mode to the ... En savoir plus
The nature of dark matter remains one of the most pressing puzzles in physics. The MAgnetized Disc and Mirror Axion eXperiment (MADMAX) is a dielectric haloscope dedicated to the search for QCD axion dark matter in the mass range of 40 - 400 µeV. The design of the experiment consists of ... En savoir plus
This paper presents the study of the simulation of mixed-mode S-parameter using COMSOL Multiphysics® RF Module. In addition, a COMSOL® application is also developed for the study of electrical connectors. We are interested in modeling electrical connectors used for data transmission ... En savoir plus
With the Release 14, the Third Generation Partnership Project (3GPP) [3GPP TR 38.913 V0.4.0, 2016] paved the way to the possibility of delivering digital television services on mobile terminals, such as smartphones and tablets, overcoming all the limitations which characterize the ... En savoir plus
