Michel Moisan

Professor Michel Moisan and his team at Université de Montréal (UdeM) explored the capabilities of various devices they patented (e.g. surfatron, surfaguide: now in the public domain) that provide plasma torches or plasma columns simply and efficiently, using radiofrequency (RF: few MHz-100 MHz) or microwaves (above 100 MHz in the present case), both commonly designated as HF fields. These original devices launch an electromagnetic surface wave that propagates guided along the plasma jet surrounded by a gas (e.g. air) or along a plasma column filling a dielectric vessel (transparent to HF field) in which it is generated.
