Ultra-wideband electromagnetic pulse propagation in a homogeneous, cold plasma

Transient Modelling of Ultra Wideband (UWB) Pulse Propagation

Transient modeling of electromagnetic pulse propagation can be traced back to the beginning of the last century, has become a powerful tool for ultra wideband (UWB) technology, and has been of great interest with a variety of applications, such as short range communication, material characterization, geophysical probing and medical imaging. When an appropriate model has been adopted for the med...

Pulse-Based Ultra-Wideband Transmitters

Ultra-wideband radio (UWB) is a rapidly developing wireless technology that promises unprecedented data rates for short-range commercial radios, combined with precise locationing and high energy efficiency. These benefits stem from the use of wide bandwidths and impulse signaling, implying high channel capacity and precise time resolution. UWB has been used for military radar and imaging since ...

Simulation of Ultra-wideband Indoor Propagation

A comprehensive simulation of ultra-wideband signal propagation in indoor environments is presented. The simulation is based on time-domain electromagnetic modeling of transmitting and receiving antennas and the analysis of wave propagation through indoor channels using the time-domain uniform theory of diffraction. The antennas are a pair of TEM horns which are modeled as arrays of vee dipoles...

An Evaluation of Ultra-wideband Propagation Channels

Evaluation of an Ultra-Wideband Propagation Channel

This paper describes the results of an ultrawideband (UWB) propagation study in which arrays of propagation measurements were made. After a description of the propagation measurement technique, an approach to the spatial and temporal decomposition of an array of measurements into wavefronts impinging on the receiving array is presented. Based on a modification of the CLEAN algorithm, this appro...
