| Abstract: |
| A pico or nano satellite is commonly applied to group spy mission. A new Micro-nano thruster (optical wave nano-thruster) has been designed to provide a propulsion ability to the pico or nano satellite， and the new technology involves both the surface plasmon polariton (SPP) and optical tweezer (OT). To verify the feasibility of the operating principle， a numerical simulation of the operation performance in several cases which include different material and structure antenna， different channel section shape and different working mediums has been conducted. Moreover， the electromagnetic field intensity， its induced gradient optical force and the total thrust of the cascading system have been calculated to verify the feasibility. The calculation results show that the optical wave nano-thruster can provide a thrust of 1μN magnitude order， which meets the need of application on pico or nano satellites. |
