This paper presents a comprehensive review, modeling, simulation, and evaluation of multipath propagation mechanisms—reflection, scattering, diffraction, and fading—relevant to 5G communication, with ...

The formation of a rainbow requires the observer to be between the sun and falling rain, with the rain in front and the sun behind. Sunlight passes from behind the observer, refracts as it enters each ...

Introduction: A model of soil mechanics is used to study the problem of reflection and transmission of an obliquely incident plane P-waveon a discontinuous interface. Based on the propagation theory ...

This work achieves the refraction and reflection of flexoelectric-induced directrons at interfaces. With identical physical properties of the media on both sides of the interface, as well as uniform ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

High-frequency signals, like those used in 5G communications, are reflected by impedance discontinuities. Their shorter wavelengths can change their impedance. When a signal arrives at an impedance ...

As a high school sophomore in 2017, Bethany Enger Cheney reveled in the stomach-churning fun that is Utah State University Physics Day at Lagoon. With thousands of her peers from Utah, Idaho, Wyoming ...

The events leading to the Biafran secession and the Nigerian Civil War itself were the most tragic and important in the history of Nigeria. They have also been silenced. Much is forgotten; what little ...
