In the past few years, metamaterial perfect absorbers (MPA) have been extensively studied due to their incredible ability to manipulate electromagnetic waves and provide a broadband, polarization-independent, and wide-angle response for a host of applications. The need for high-performance terahertz regime MPA is increasing for both the commercial and the military applications to provide ...

Liquid-crystal elastomers (LCEs)  have attracted a great attention in recent years due to their high potential in a wide range of applications, from microfluidics components  to artificial muscles . The photo-mechanical response of LCEs is due to their constitutive photo-sensitive molecules, which change shape when absorbing part of the incident light. These microscopic deformations can ...

Nuclear Quadrupole Resonance (RQN) is a radio frequency (RF) spectroscopic technique that is used to detect quadrupole nuclei such as Nitrogen-14. NQR was found to be a good candidate for detecting narcotics, explosives and medicines . However, due to its low sensitivity the use of NQR is still limited. One way to increase the sensitivity is to improve the RF coil by means of a better RF ...

In thin-film solar cells (a-Si:H, µc-Si:H, CIGS, etc.) scattering of light is very important to increase absorption of light in the active layers of solar cells. Today the most efficient thin-film solar cells are designed or deposited on random textured transparent conductive oxides (TCO). In order to study the scattering properties of the surface texture we have developed a numerical model in ...

This paper describes the Virtual Prototyping based on a COMSOL Multiphysics® simulation for a novel Microwave Fin Taper (FT) Spatial Power Combiner (SPC) Amplifier. The analyzed system is waveguide (WG) based, and uses FT Probes to convert the energy of a rectangular WG EM fundamental mode to a Microstrip Transmission Line TEM mode, in order to be amplified by a Solid State Power ...

Design of Microwave Resonance Cavity (MRC) to generate non-thermal plasma to treat NOx and SOx from marine diesel engine is presented in this paper. Microwave frequency of 2.45GHz is used generate the required plasma. A number of wave guides are used to transfer the microwave energy into to MRC from the microwave source. COMSOL multi-physics software is used to model the waveguides and to ...

In this paper, we present a 2D axisymmetric self-consistent plasma fluid model for microwave plasmas operating in argon. The model was developed using COMSOL Multiphysics and its Plasma Module. Plasma, flow, heat and electromagnetic equations solved self-consistently. The effect of the pressure on the plasma parameters is studied over a wide range of pressures going from 10 mbar to ...

Non-communicable diseases (NCDs) have globally become a prevalent problem, accounting for more than 60% of the mortality worldwide. NCDs impose socioeconomic consequences to low-income countries as 80% of NCD deaths occur in such countries [1, 2]. The World Health Organization has necessitated that cost-effective preventive measures, which have an immediate impact on the burden at population ...

The plasma enhanced chemical vapor deposition process with a linear plasma source and the frequency range up to 140 MHz developed by Dresden University of Technology and FAP GmbH Dresden enables a fabrication of thin film silicon layers at very high deposition rates. However, an increase of the plasma frequency reduces the electromagnetic wavelength. Therefore, the electric field distribution is ...

Vacuum window is required in the millimeter wave transmission line in ITER*. It is to be designed to minimize the microwave reflection while keeping a robust and safe approach to meet the requirements. We have studied transmission characteristics of various dielectric materials over D-band frequency range (110-170 GHz) using RF Module of COMSOL Multiphysics®. Purpose of this study is to choose ...
