Electromagnetic field strength distribution representation device uses absorber foil converting HF energy into heat detected by temperature sensor matrix

摘要

The field strength distribution representation device uses an absorber foil for converting HF energy into heat, with measurement of the surface temperature of the foil via a matrix of temperature sensors. The HF sensor (1) may be placed on a positioning table, with the measured values from the temperature sensors fed to a personal computer, for representation of the field strength distribution on the computer monitor.
