WebA common measure of exposure is the Specific Absorption Rate (SAR), the rate of energy absorption in tissue, measured in watts per kilogram of tissue. C95.3, Recommended … WebYou could build a simple crystal radio with a tank circuit to show resonance which is how you would receive the power of a radio wave to begin with. You could get creative and make a simple crystal radio where you replace the diode with a transistor, then use a second tank circuit to tune in a close by, strong station to bias the transistor.
