Resonant Cavity Electrospray Systems and Methods

A method for atomizing fluids, the method comprising:

• transmitting one or more radio frequency signals to a resonant microwave cavity provided by a power source;
• amplifying a voltage of the one or more radio frequency signals within the resonant microwave cavity;
• generating an electric field at a first end of a field concentrating pole;
• supplying a fluid to the first end of the field concentrating pole through a fluid supply line;
• atomizing the fluid at the first end of the field concentrating pole, wherein the electric field atomizes the fluid;
• and
• spraying the atomized fluid through a nozzle disposed at an end of the fluid supply line.

An electrospray system for atomizing fluids, comprising:

• an electrospray device comprising:
• a body defining a resonant microwave cavity, wherein the body comprises a radio frequency inlet configured to provide a radio frequency signal received from a power source into the resonant microwave cavity, wherein the resonant microwave cavity is configured to amplify a voltage of the radio frequency signal;
• a field concentrating pole disposed within the resonant microwave cavity configured to concentrate the amplified voltage at a first end of the field concentrating pole to form an electric field;
• a fluid supply line configured to provide a fluid disposed within the field concentrating pole;
• and
• a nozzle disposed at an end of the fluid supply line;
• the power source;
• and
• a controller configured to instruct the power source to supply power to the electrospray device.
