Far-field Measurement

Far-field measurement refers to analyzing how electromagnetic waves, such as radio or light signals, behave at a distance from their source. In this region, the waves spread out and their properties, like direction and strength, can be accurately characterized without interference from near-field effects. This is essential for understanding antenna performance, radar, and communication systems, as measurements taken in the far-field provide a clear picture of how signals radiate into space. Typically, these measurements are made at distances many times the size of the source to ensure accuracy and clear data representation.
