Multiple Time-Domain Diffraction for UWB Signals

In this work the time-domain solution for transmission through a multilayer wall structure has been presented. A time-domain transmission coefficient formulation for transmission through an interface between two low-loss dielectric mediums with different electrical properties is derived. Both hard and soft polarizations are considered. A novel ray tracing algorithm for multilayer wall structure has been presented with accuracy of ray-traced path as close as order of 10 −5 . Further, in depth formulation for actual refracted angles for different layers of the wall has been presented and exact frequency-domain formulation for transmitted field at the receiver has been obtained. The exact formulation has been simplified under the condition of low loss assumption and this simplified formulation has been converted to time-domain formulation using inverse Laplace transform. The proposed time-domain solution has been validated with the inverse fast Fourier transform of the corresponding exact frequency-domain solution. Further the computational efficiency of both the methods has been compared.

“…UWB communication systems employ the transmission and reception of very short duration pulses, usually a fraction of 1 ns [2][3][4][5], which cover extremely large bandwidth in the frequency-domain (FD). The possibility of very short duration pulses makes UWB signals resilient to multipath phenomena.…”

“…Therefore, it seems to be more convenient to analyse UWB systems in the time domain [13,14] by defining some useful counterparts of the standard frequency-based antenna parameters [11,12,[15][16][17]. An example of a design procedure partially performed in the time domain can be found in [18], where a geneticbased optimization of a simplified version of the volcano smoke antenna is described.…”

Abstract-In this paper, an approach for the synthesis of UltraWideband (UWB) antenna systems in the time domain is proposed.Starting from the definition of suitable time-domain performance indexes, the design process is based on a spline representation of the antenna shape and a Particle Swarm Optimization (PSO) aimed at matching optimal radiation and electrical conditions. The effectiveness of the proposed time-domain technique is assessed by means of both numerical and experimental results.
