Electromagnetic waves show rapid development in electronics, telecommunications, and the military. One of efforts to overcome effects electromagnetic interference is by developing microwave-absorbing materials. Barium hexaferrite best candidate for as an absorber material. Microwave absorption barium can be increased through Mg-Al doping reducing particle size. This study aimed analyze sonicati...

The hierarchical MoS2/CoNi composites were successfully synthesized by a two-step hydrothermal method. large surface area of the MoS2 enhances dispersivity CoNi nanoparticles and formation abundant interfaces, which make an important contribution to dielectric loss, introduction improves impedance matching introduces magnetic can improve absorption performance electromagnetic waves. Through cal...

High-entropy MXenes, as a new emerging class of materials, possess diverse compositions, unexpected physicochemical characteristics and great potentials for electromagnetic (EM) wave absorption. Herein, two single-to-few-layer high-entropy (Mo0.25Cr0.25Ti0.25V0.25)3C2Tx (Mo0.2Cr0.2Nb0.2...

We present an extension of the Bérenger Perfectly Matched Layer with additional terms and tunable coefficients which introduce some asymmetry in the absorption rate. We show that the discretized version of the new PML offers superior absorption rates than the discretized standard PML under a plane wave analysis. We also introduce a new method for applying the Mesh Refinement technique to electr...

voltages and currents are induced into electronic circuit boards as electromagnetic waves are radiated on them. the strength of induction depends on the wavefront and the circuit board characteristics. in this paper, by solving maxwell’s equations using fdtd method and then by extending it by three dimensional simulation using the gpml criteria for boundary conditions and tf/sf technique, effec...

The magnetic and electromagnetic wave absorption behavior of a flexible ironnanoparticle reinforced polyurethane nanocomposite is reported. Surface-initiatedpolymerization (SIP) method was utilized to fabricate high quality nanocomposites with uniform particle distribution and tunable particle loading (up to 65 wt.%). The enhancement of coercive force is observed when the nanoparticles are embe...

The paper presents the numerical evaluation of the electroencephalogram (EEG) electrode artifacts that are caused during exposure to electromagnetic fields (EMF), in volunteers study. The scope of the study is to differentially present the electromagnetic (EM) power absorption and local Specific Absorption Rate (SAR) distribution, with and without the electrodes. Versions of two basic exposure ...

The absorption, reflection, and transmission of electromagnetic waves by a nonuniform plasma slab immersed in an ambient uniform magnetic field of various strengths are studied in this paper. The effects of the plasma parameters and magnetic field strength on the absorbed, reflected, and transmitted power are discussed. The magnetized nonuniform plasma slab is modeled by a series of magnetized ...
