The capacitive field treatment on the wheat grains designed in the Radio Frequency (RF) region is discussed in this paper. The pattern of power dissipation and Specific Absorption Rate (SAR) value within the wheat grains is determined using the designed model of capacitor and the wheat grains in COMSOL. Major problem in the Agriculture are the pests which infest the seeds, crops and end products like fruits, vegetables and grains. SAR and the power dissipation within the grains are found using COMSOL MULTIPHYSICS. Result of simulation shows that power dissipation and the SAR varies with the variation in the terminal voltage at the capacitor plates. RF treatments are very effective for protecting the grains from the possible infestations. This methods can also be implemented for post-harvest storage of the grains. The RF or Microwave (MW) treatment is an area of research for attractive quarantine treatment because it is quick and safe, and operation costs are comparable to chemical fumigation. Keywords—Specific Absorption Rate, Power Dissipation Pattern, Capacitive Heating, Capacitive field, RF range, Infestation of grains.
