Specific Absorption Rate Estimation for a Typical Hibiscus Flower Model as per ICNIRP Electromagnetic Guidelines

Specific Absorption Rate is a measure of the rate at which electromagnetic energy is absorbed by a living dielectric object while exposed to microwave radiation. Specific Absorption Rate estimation in different standard human phantoms is commonly performed to safeguard human health from possible hazards of cell phone radiation. Plants and flowers that possess reasonably high dielectric properties are also continuously exposed to electromagnetic radiation from wireless communication antennas installed on towers and high rise buildings. Hence, considerably high electromagnetic energy absorption rate is expected among different plants and flowers too; and consequent investigations on possible biological effects should also be carried out. With this background, this work aims at dielectric properties characterization of hibiscus flowers and estimating Specific Absorption Rate for a typical hibiscus flower structure at 2.45 GHz ISM band. Linearly polarized plane wave irradiation has been impinged as per global electromagnetic regulatory guidelines prescribed by International Commission on Non¬Ionizing Radiation Protection. Estimated maximum local point, 1g averaged and whole body averaged Specific Absorption Rate data have been reported and observed to be of significant level.
