  1. 2. Circuit component that converts alternating current (AC) into direct current (DC).
  2. 4. Purpose-built technology that transfers electrical power without physical wires.
  3. 5. RF energy that is naturally present in the surrounding environment rather than intentionally transmitted for harvesting.
  4. 8. Component that receives electromagnetic waves and converts them into an electrical signal
  5. 9. what is used to improve ordinary inductive coupling?

  1. 1. the loss in power density of an electromagnetic wave as it propagates through an unobstructed, line-of-sight path in free space.
  2. 3. Transfer of energy from a transmitter to a receiver through a changing magnetic field.
  3. 6. Electrical current that changes direction and magnitude over time.
  4. 7. The number of wave cycles that pass a fixed point in one second.
