background: both increased arterial stiffness and hyperuricaemia are associated with elevated cardiovascular risks. little is known about the relations of serum uric acid (ua) level to regional arterial stiffness and wave reflection. the aim of the study was to investigate the gender-specific association of serum ua and indices of arterial function in a community-based investigation in china. m...

This paper aims to perform experimental validation of RF–plasma interaction behaviors for the purposes wave transmission and reflection. Wave reflection from plasma is interest as it finds applications in pulse compression RF polarizer-based systems. Simulations are performed using a combination Magic3D COMSOL multiphysics characterize plasma–wave discharge tube properties. The goal generate wi...

Electromagnetic Band Gap (EBG) structures are nonperiodic structures that show unique electromagnetic features, such as frequency band gap for surface waves and in-phase reflection coefficient for incident plane waves, which makes them desirable for low-profile antenna designs. A very innovative topic for antenna scientists and engineers are the applications of EBG structures in antenna designs...

This paper is concerned with the effect of pure shear on the reflection from a plane boundary of infinitesimal plane waves propagating in a half-space of incompressible isotropic elastic material. For a special class of constitutive laws it is shown that an incident plane harmonic wave propagating in the considered plane gives rise to a surface wave in addition to a reflected wave (with angle o...

A problem of reflection and transmission of a plane shear wave incident at a corrugated interface between transversely isotropic inhomogeneous and visco-elastic half-spaces is investigated. Applying appropriate boundary conditions and using Rayleigh’s method of approximation expressions for reflection and transmission coefficients are obtained for the first and second order approximation of the...

This paper presents a Matlab-based graphical user interface (GUI) that allows the simulation of the propagation of an electromagnetic wave in a 2-D infinite space. The homogeneous, isotropic medium is modeled by using the Finite– Difference Time-Domain technique and its infinity is modeled with the Perfectly Matched Layer. The GUI provides different ways of displaying the graphical results: 3-D...
