loop antenna: printed circuit with 2 metallic lines printed on dielectric substrate
During exposure, rats were restrained in rockets made of 5-mm-thick Plexiglas and consisting of a cylinder (6 cm diameter, 15 cm length) and a truncated cone (3 cm length) in which the rat inserted its head. The loop antenna was placed against the cone directly above the rat's head. The four rockets for simultaneous exposure were separated from each other by a double layer of a 12 cm absorbing material to prevent interference from one antenna to another.
The performances of exposed rats were compared to those of sham-exposed and cage-control rats.
The SARs were determined experimentally using either a Vitek probe for the measurement of temperature rises or an electric field probe. FDTD calculations were done on homogeneous and non-homogeneous phantoms and the agreement among the three independent methods was very good (see reference article).
