Probing Lossy Fields in Electromagnetic Spheres and Cylinders

Distributions of electric fields in lossy spheres and infinite lossy cylinders simulating biological objects were measured at 350, 920 and 2450 MHz. The measurements were performed in a computer-controlled scanning system using three different implantable nonperturbing probes. The results are compared with theory, and use of Iossy spheres and cylinders for calibration of implantable probes is quantitatively evaluated.
