Latest Patents

Dimitris is credited with one key patent: the Micro-cathode matrix arc thrusters. This unique matrix thruster is designed specifically for the repositioning and stabilization of CubeSAT satellites. It consists of a conductive plate featuring an opening and a multitude of wires embedded within that opening. Power is supplied to the thruster via an electrical connection to the conductive plate or the wires through an inductor. The innovative design employs an electrical switch to create a current change, producing an electric potential spike that initiates an arc discharge between one of the wires and the conductive plate. This process generates plasma that ejects cathode particles, enhancing satellite maneuverability. By utilizing multiple wires, such as four titanium wires, the design effectively extends the operational lifetime of the thruster, as it allows each wire to restore the inter-electrode film necessary for consistent plasma generation.
