FMR spectra of the periodic microstructures (one-dimensional magnonic crystals, 1D MCs) were obtained using COMSOL with use partial differential equation interface. Results of these calculations were successfully compared with an experimental data for Damon-Eshbach (DE) and Backward-Volume (BV) geometries. The presented tool allows to analyze periodic structures with various geometries and ...

Microwave drying of fruits and vegetables in a domestic oven has been found to result in large textural changes in the product such as puffing, crack formation and even burning due to the inhomogeneous heating of the microwaves. Microwave drying of potatoes is a complex interplay of mass, momentum and energy transport. Three phases are considered in the system: solid (skeleton), liquid (water) ...

Upon operation, the magnetron of a conventional microwave oven induces a pattern of standing electromagnetic waves in the oven cavity. Interactions with the field define the amount of energy absorbed in a part of a food object within the cavity. The well-known inhomogeneous heating produced in a microwave oven is partially an effect of the standing waves’ natural nodes and antinodes and ...

Radiofrequency ablation is one of the common methods used to treat pain, movement or mood disorders. It bases on the electromagnetic energy provided to the selected tissue when an alternating current is applied. The resistive heating produced in this process provokes temperature rise in target tissue and generates lesion for intended therapeutic effects. However, in case when no tissue damage is ...

Introduction Computer simulations are widely used for the interpretation and inversion of electromagnetic measurements in well logging. Until recently, simulated logs have been computed with approximate 1D or 2D models. By using the COMSOL® RF Module installed on a cluster, we show that a full 3D finite-element simulated log can be obtained within an acceptable turnaround time. Use of ...

Introduction: Single-photon detectors capable of ensuring high fidelity read-out of quantum information delivered via photons of specific polarization are crucial in QIP . Our previous studies have shown that different types of one dimensional plasmonic structures enhance the absorptance of p-polarized light [2, 3]. The purpose of present study was to optimize four different types of ...

In this paper, we will present simulation results obtained using COMSOL RF module for the current along a wire antenna in both frequency and time domains. The structure is excited through a lumped (voltage or current) source at its center. For the frequency domain simulations we compare the results with the Numerical Electromagnetics Code (NEC-4) and for the time domain results we compare them ...

Patch antennas are widely used in communications links with unmanned aerial vehicles. Their hemispherical send and receive patterns enable the systems to maintain radio frequency contact over a wide range of vehicular attitudes. A microstrip-fed design offers other attractive features including lightweight, inexpensive, and a 3-D structure that can be easily integrated into the fuselage. This ...

Introduction: This study presents the 3D electromagnetic model in layered media using induction logging tool. This algorithm utilizes electromagnetic wave frequency domain (EWFD) interface of Maxwell equations. Electromagnetic methods are popular tools for the measurement of resistivity (or conductivity) of the Earth formation. The purpose of our study is to show the effect of conductivity and ...

Introduction: In inductively coupled plasma (ICP) systems the inductive antenna is coupled to the excited plasma inside the low pressure gas reactor. A multi-ICP system can be used for increased area processing and provide additional variables for controlling the plasma. However, assembling the source from individual sources changes the symmetry of the system. Simulation of plasmas in ...
