Since the optical band does not overlap with existing radio frequency bands, there is no electromagnetic interference Compared to their RF siblings, light waves
Electromagnetic Radio Frequency Transits water/air boundary Transits water/ seabed boundary Signal passes through ice Unaffected by water depth
The electric and magnetic fields oscillate as sine waves and may be amplitude modulated at the power supply frequency For any particular RF heater application
