Abstract

Time-temperature profiles of a specimen exposed to microwave radiation are presented. Using measured cooling curves to determine the cooling coefficient and the absorption factor for different power densities of exposure, time temperature profiles during exposure and, therefore, the amount of energy absorbed by the specimen can be mathematically determined. After cooling coefficients and absorption factors have been obtained for specific geometry, time-temperature profiles and energy absorption can be calculated for any exposure value. This paper presents the technique and explains the usefulness of the technique for determining energy absorption by biological specimens when exposed to microwave radiation of a known power density.
