Cross-Polarization

Cross-polarization refers to a situation in optics and radio waves where polarized waves (waves with a specific orientation) are transmitted and received with perpendicular orientations. For example, if a signal is sent with vertical polarization, a receiver tuned to horizontal polarization would detect little to no signal. This technique helps reduce interference and improve signal clarity by ensuring that only desired polarized waves are received, enhancing communication quality. Cross-polarization is widely used in satellite communications, radar, and wireless systems to minimize unwanted signal overlap and maximize signal integrity.
