radiofrequencybased
Radiofrequency-based, or RF-based, describes systems, devices, or methods that rely on radiofrequency electromagnetic fields for operation. The radiofrequency band covers roughly 3 kHz to 300 GHz, with many practical applications concentrated in the kilohertz to gigahertz range. RF-based approaches use antennas or coils to transmit and receive energy, and often modulate or alter the signal to transmit information or deliver energy.
Core components include RF sources (oscillators and amplifiers), impedance-matched antennas or coils, and receivers with demodulation
In medicine, RF-based methods include ablation and hyperthermia, where high-frequency energy heats targeted tissues to treat
In communications and sensing, RF-based technologies enable wireless transmission and identification (RFID, NFC, Wi-Fi, cellular networks),
Safety and regulation address exposure limits, spectrum allocation, and device certification. Standards bodies such as ICNIRP,
