Composition for a solid state material, in bulk and in thin film form, that provides relatively high dielectric permittivity that is tunable with variable electrical field bias, relatively low loss tangent and low leakage current for microwave applications. In a first embodiment, the material is Ba Sr Ti M O , where M is a substance or mixture including one or more elements drawn from a group consisting of Ta, Zr, Hf, V, Nb, Al, Ga, Cr, Mo, W, Mn, Sc and Re, and the indices x and y satisfy 0x1 and 0y1. A preferred choice is M=Ta, V, W, Mo and/or Nb. In a second embodiment, the material is Ba Sr Ti Ta M O , where M is a substance or mixture including one or more trivalent elements drawn from a group consisting of Al, Ga and Cr and the indices x, y and z satisfy 0x+z1 and 0y1.

G01V 300

324300, 324304

Methods for spatially resolve spin resonance detection in a sample of material, with a resolution as small as 0. 5 m-1 mm. In one embodiment, a coupler having at least one pair of degenerate orthogonal modes provides an evanescent input signal along one coupler axis to the sample, to which a magnetic field is applied, and senses a spin interaction signal along another coupler axis. In another embodiment, an evanescent input signal is applied to the sample along one of two identical transmission line resonators, and a difference of the two resonator signals provides a spin interaction signal. In another embodiment, a polarized laser beam provides an evanescent input signal to the sample, and the spin interaction signal is sensed according to a second beam polarization direction. Certain ferromagnetic or ferrimagnetic molecules, such as YIG, can be used to tag selected chemical and biological molecules, using spatially resolved spin resonance detection for interrogation.

Novel systems of an evanescent microwave probe (EWP) are disclosed, which enable measurements of physical properties of a sample with enhanced sensitivity and resolution, simultaneously. In one embodiment, new shielding features are added to the probe (which may be of either a sharpened tip or loop configuration) to reduce the effects of residual far field radiation, while maintaining the probe section that extends beyond the shielding aperture of the resonator. To further increase the sensitivity of the instrument, an automatic gain-controlled active feedback loop system may be added to the probe resonator to form a self-oscillator. This new active circuit feature significantly increases the effective Q of the resonator probe, enhancing the sensitivity of both the frequency and Q measurement.

Disclosed are fixed solar-electric modules having arrays of solar concentrator assemblies capable of separately tracking movements through one or two degrees of rotational freedom to follow the movement of the sun daily and/or seasonally. The concentrators can include optical elements to direct and concentrate light onto photovoltaic and/or thermoelectric receivers for generation of electric current.
