Abstract
A resonator structure including a first resonator having a first resonator loop formed by a hollow channel with conductive walls and a second resonator having a second resonator loop formed by a hollow channel with conductive walls. The first resonator loop and the second resonator loop intersect so that the first and second resonator loops are substantially shielded to prevent coupling of high frequency energy between the first and second resonator loops. The orthogonally of the resonator loops can be adjustably control in either of two orthogonal axes. A sample is placed in a space defined by the intersection of the first and second resonator loops. High frequency energy is applied to the first resonator. The angle at which the second resonator loop intersects the first resonator loop is selected to substantially decouple the first resonator from the second resonator. A detector circuit detects the high frequency energy in the second resonator loop and supplies the detected signal for subsequent analysis.
