Abstract
This paper describes a coupled re-entrant cavity system which is designed to provide an electric field distribution capable of generating levitation forces on a conducting plate located in the near-field of two or more non-radiating coupling apertures. Re-entrant cavities are used to maximise the levitation field at these apertures which are placed at the re-entrant cavity gap. The system represents a particularly complex electromagnetic boundary value problem and consequently the arrangement has had to be modelled using a finite element simulation package in order to secure a design. Simulation results from the finite element model are compared with the measured results from the final design.
