This study report is divided into two parts. In first part, analysis of physical and chemical properties of various shielding materials are done and shielding effectiveness of various materials with respect to frequency are compared. On the basis of shielding effectiveness obtained, best material for shielding is estimated. After estimation of best material for shielding, special technique is incorporated to intensify the capability of shielding of same material. In second part, an electronic circuit is implemented in electromagnetic wave environment. After observing harmful effects of electromagnetic radiation on electronic circuit such as distorted output, the electronic circuit is shielded from electromagnetic radiation by encapsulating the electronic circuit with the help of a shielding enclosure. In this study we observed that a novel method for supplying power by using the power in the surrounding electromagnetic waves was utilized. Similarly in flight, recharging drones when they are dispersed throughout wide and lonely places can be time-consuming. Drones utilize electromagnetic waves to recharge sensors. As the whole electronic circuit is fully shielded from electromagnetic waves environment, we cannot utilize the enclosing electromagnetic wave in supplying power to the electronic circuit. The electronic circuit can be configured in such a way that it will be able to utilize the power from the surrounding electromagnetic radiations without effecting the characteristics of electronic circuit.
