Abstract The Old City Cemetery in Murfreesboro TN is a 3.5-acre cemetery site which encompasses the buried archaeological remains of the 1820 Old First Presbyterian Church and associated burial sites. To understand buria...

In this paper, the two-dimensional one-body Casimir effect is analyzed on the example of square-shaped nanocells. In the classical one-dimensional two-body Casimir effect a Casimir force appears between two plates as a d...

Abstract This study explores the valorization of ceramic waste (CW) and waste tire particles in the development of eco-friendly cementitious tiles for outdoor roof shielding applications. CW, sourced from industrial bypr...

Cherenkov radiation (CR) is the electromagnetic shockwaves generated by the uniform motion of charged particles at a velocity exceeding the phase velocity of light in a given medium. In the Reststrahlen bands of hexagona...

Abstract This study aims to investigate the influence of parasitic capacitances within half-bridge SiC power metal oxide semiconductor field effect transistor (MOSFET) modules, including input capacitance (Ciss), output ...

This paper presents an analytical formalism that allows for a description of a variety of non linear optical phenomena occurring when an electromagnetic wave propagates through a nematic liquid crystal. First, by using o...

Abstract Background Recent WHO-commissioned systematic reviews have concluded with “high certainty” that exposure to radiofrequency electromagnetic fields (RF-EMF) increases cancer risk and reduces male fertility in ...

External ventricular drain (EVD) placement is a standard neurosurgical procedure for cerebrospinal fluid diversion and intracranial pressure monitoring, yet conventional freehand techniques are associated with substantia...

Abstract An alternative theoretical approach is presented for improving the understanding of the scattering properties of simple negative-index and plasmonic spheres. The Mie scattering coefficients are broken up into tw...

In this paper, we review and discuss how the recently discovered two-dimensional (2D) Dirac materials, particularly graphene, may be utilized as new efficient platforms for excitations of propagating and localized surfac...

This work describes the design and optimization of a printed circuit board containing a rectangular half-loop coil designed to apply radio frequency signals on micrometric diamond crystals. The structure was optimized to...

As an aircraft component is subjected to tensile/torsional/bending forces and heat cycles during operation, non-destructive inspection programs have been mandated by aviation regulatory authorities and component manufact...

Abstract In this study, a rib waveguide is used in the design of a plasmonic sensor. The structure consists of a dielectric substrate constituted of tantalum pentoxide (Ta2O5). On top of this substrate, a superstrate wit...

In this article, the basic principles and the main applications of Huygens’ metasurfaces (HMSs) are reviewed from microwaves to optics. In general, HMSs comprise a thin layer of orthogonal electric and magnetic dipoles...

Abstract It is shown that proper representation of transmitting and receiving antennas in indoor environments are decisive for accurate prediction of electromagnetic power transfer parameters using the standard 3D-FDTD m...

The demand for advanced camouflage technology is increasing in modern military warfare. Multispectral compatibility and adaptive capabilities are increasingly desired features in camouflage materials. However, due to the...

Illumination of noble metal nanostructures by electromagnetic radiation induces coherent oscillations of conductive electrons on their surfaces. These coherent oscillations of electrons, also known as localized surface p...

Abstract Normally the physical dimensions of the taper transition that realizes the impedance matching between the impedance of the feeding line built in microstrip line technology and the impedance of the component buil...

For the molten pool behavior in K-TIG welding, the Level-Set method was used to track the changes in the free surface of the molten pool, and a two-dimensional transient numerical calculation model for stationary welding...

Radiation from both natural and artificial sources is an inescapable and undeniable reality of human existence. Aside from exposure to radiation from a wide variety of natural sources including background ionizing radiat...

Plasmonic nanoantennas have the ability to confine and enhance incident electromagnetic fields into very sub-wavelength volumes, while at the same time efficiently radiating energy to the far-field. These properties have...

Abstract This paper proposes an optimal design for a surface mounted permanent magnet synchronous machine (SM-PMSM) based on parametric optimization process to reduce the on-load Back-EMF distortions caused by an increas...
