    • The present invention provides a communications transmitter (8), which is suitable for wireless communication. The transmitter (8) at least comprises a transmitting electrode (10), a modulator for modulating an electrical charge to apply to the transmitting electrode (10) with an information-bearing signal, a charger for applying the modulated charge to the transmitting electrode, a source (18) of ionising radiation for at least partially ionising a body of ionisable gas (12, 12') in contact with the transmitting electrode (10), and a gas pressure pump for imparting a velocity, v, to the body of gas (12, 12') to direct it away from the transmitting electrode (10) more rapidly than a natural diffusion velocity of the body of gas. This transmitter (8) can be incorporated into a wireless communications apparatus, along with a receiving electrode (16), a channel disposed between the transmitting electrode (10) and the receiving electrode (16) for transporting the body of ionisable gas (12, 12') from the transmitting electrode to the receiving electrode, an electrical charge-measuring device for measuring an electrical charge on the receiving electrode (16), and a demodulator for demodulating the electrical charge measured on the receiving electrode (16), in order to recover the information-bearing signal. The present invention also provides a corresponding method of wireless communication using an at least partially ionised body of gas (12) ( i.e. a plasma) as the communication medium, which is substantially immune to external radio-frequency sources of electromagnetic radiation, thereby rendering it invulnerable to jamming or interference. Moreover, since the plasma is electrically charged, it can also be used to transmit electrical power along with information, in simultaneous wireless information and power transfer (SWIPT).
