Cold Plasma Waves

Cold plasma waves refer to oscillations in a low-temperature plasma, which consists of charged particles like electrons and ions. Unlike hot plasmas, cold plasmas have less kinetic energy and are often found in environments such as space or certain laboratory settings. These waves occur when the charged particles move back and forth, creating electrical and magnetic fields. Cold plasma waves play a key role in various natural phenomena, such as auroras, and have applications in technologies like semiconductor manufacturing and plasma medicine, where they are used for sterilization and wound healing.
