|Pulse width||6 µs|
|Rise time||0.9 µs|
|Fall time||0.9 µs|
Pulse repetition rates of 0, 0.59, 1.18, and 2.79 Hz were applied. The square wave equivalent pulse width calculated from pulse energy and peak power was 5.59 µs. The width of the entire sideband was less than 20 MHz.
|Distance between exposed object and exposure source||7.6 cm|
|Setup||Monkeys were restrained in a PVC chair with head restraints. An open-end WR650 waveguide was used as an antenna to provide vertical E and horizontal H polarizations. The configuration allowed localized exposure limited to head and neck of the monkey.|
|Sham exposure||A sham exposure was conducted.|
No evidence of degenerative changes and electroretinography (ERG) depression was seen. Retinal injury is very unlikely at 4W/kg. Functional changes that occur at higher R-SAR are probably reversible since no evidence of histopathologic correlation with ERG changes was seen.
