Theoretical investigations have been carried out on the effects of non-ionizing electromagnetic (EM) radiation on pollen grains at sub-THz frequencies. To carry out the investigation, a realistic three dimensional electrical model of pollen colony has been developed and placed between a pair of dipole antennas designed at sub-THz frequencies. The model is simulated using Finite Integral Time (FIT) based commercially available software CST Microwave Studio®. EM energy absorption in pollen grains increases significantly when applied frequency changes from quasi static to resonating modes. Initially, the resonance frequencies have been detected by changes in scattering parameters. Then phase distributions of E field and H field at the different planes inside the pollen grains have been investigated. Results obtained from the simulations show that significant EM energy is absorbed inside the pollen grains at frequencies close to their electrical resonance frequencies. Results obtained from the thermal simulations show that significant portion of the absorbed EM energy is converted into the thermal energy inside the pollen grains. Controlling the radiated EM energy, rise of temperature inside the pollen grains can be controlled. [ABSTRACT FROM AUTHOR] |
