RFsähkökenttä

RFsähkökenttä refers to the electric field component of radio frequency (RF) electromagnetic radiation. Radio frequencies span a broad range of electromagnetic waves, typically from about 3 kilohertz to 300 gigahertz. When these waves propagate, they consist of oscillating electric and magnetic fields that are perpendicular to each other and to the direction of propagation. The RFsähkökenttä is the oscillating electric field within this radiation.

The strength of an RFsähkökenttä is often measured in volts per meter (V/m). Exposure to RFsähkökenttä can occur from various sources, including radio transmitters, mobile phones, Wi-Fi devices, and microwave ovens. The interaction of RFsähkökenttä with biological tissues is a subject of ongoing research, with a focus on understanding potential thermal and non-thermal effects. Regulatory bodies establish exposure limits to ensure public safety.

Understanding the RFsähkökenttä is crucial in fields such as telecommunications, where it is essential for transmitting and receiving signals, and in electromagnetic compatibility (EMC) testing, which assesses how devices interfere with or are affected by electromagnetic fields. The behavior and characteristics of the RFsähkökenttä are governed by Maxwell's equations.
