Nonresonant Perturbation Measurement of Antenna Electromagnetic Field Configurations for Biomedical ApplicationsFootnote

Abstract

The nonresonant perturbation technique has been used to develop the measurement of antenna electromagnetic field configurations for medical applications. Antenna near-field configurations and the contour patterns in phantom materials have been analysed numerically and experimentally measured. This study has shown both methods to be in fair agreement. The penetration depth naturally depends on lossy dielectric properties through "2a" for wave propagation, and it also depends on the relative permittivity of the medium and the antenna form, the two factors causing the effective penetration distance to be less than the plane wave value.
