A planar resonator and method of manufacture provides contactless power transfer using at least two electrically isolated axis aligned conductive across the transfer interface in a coupled inductor or transformer configuration. Signal or power transfer is then accomplished by coupling of magnetic flux.

The IOET and the first and second spiral-shaped conductors have a predetermined self-resonant frequency. The planar power resonator stores electric energy in the IOET, and at predetermined frequencies, the arrangement of the first and second spiral-shaped conductors and the IOET permits transfers of magnetic flux and electrical energy between the first and second spirals across the IOET.

Improved convergence in the volume-integral method (VIM) of calculating electromagnetic scattering properties of a structure is achieved by numerically solving a volume integral equation for a vector field, F, rather than the electric field, E. The vector field, F, may be related to the electric field, E, by a change of basis, and may be continuous at material boundaries where the electric field, E, has discontinuities. Convolutions of the vector field, F, are performed using convolution operators according the finite Laurent rule (that operate according to a finite discrete convolution), which allow for efficient matrix-vector products via 1D and / or 2D FFTs (Fast Fourier Transforms). An invertible convolution-and-change-of-basis operator, C, is configured to transform the vector field, F, to the electric field, E, by performing a change of basis according to material and geometric properties of the periodic structure. After solving the volume integral for the vector field, F, an additional post-processing step may be used to obtain the electric field, E, from the vector field, F. The vector field, F, may be constructed from a combination of field components of the electric field, E, and the electric flux density, D, by using a normal-vector field, n, to filter out continuous components.

Two TE modes whose electric-field rotating planes have a perpendicular relationship are coupled independently of the coupling between two TM modes whose electric-field directions have the same respective perpendicular relationships. In a multimode dielectric resonator device producing four modes: TM01δ_x mode, TM01δ_y mode, TE01δ_x mode, and TE01δ_y mode, protrusions (Pe1), (Pe2) are disposed on an upper-layer (La) and a lower-layer of a dielectric core (1) to cause a difference in effective dielectric constants of individual parts through which even-mode and odd-mode electric flux of the TE coupling modes passes. A protrusion (Pc) is formed on a middle-layer Lb of the dielectric core (1) such that the effective dielectric constants of the parts through which even-mode and odd-mode electric flux of the TM coupling modes pass become substantially equal. Thereby, the TE01δ_x mode and TE01δ_y mode are coupled while restraining the coupling of the TM01δ_x mode and the TM01δ_y mode.
