Abstract
An in vivo exposure system, based on a TEM cell designed to operate at 900 MHz, has been numerically and experimentally characterized at 2.45 GHz. Aim of the study was to evaluate the influence of higher order modes on the field homogeneity. Results evidence a good agreement between the simulated and measured data sets further evidencing a negligible influence of the higher orders model on the transversal TEM cell planes. The final outcome seems that the system can still be efficiently used to expose small animals in the Wi-Fi band, provided they are properly placed in correspondence to the maxima of the electric field along the guide. © 2012 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
