    Abstract: Techniques for implementing series-fed antenna arrays with a variable dielectric waveguide. In one implementation, coupling elements with optional controlled phase shifters are placed adjacent each radiating element of the array. To avoid frequency sensitivity of the resulting array, one or more waveguides have a variable propagation constant. The variable waveguide may use certain materials exhibiting this phenomenon, or may have configurable gaps between layers. Plated-through holes and pins can control the gaps; and/or a 2-D circular or a rectangular travelling wave array of scattering elements can be used as well.

    Abstract: A solar energy collector includes a prism coupled waveguide and a cladding material layer coextensive with the waveguide core. Photovoltaics (PVs) are disposed within the cladding layer, with the PVs active in at least two wavelength ranges. The PVs are further spaced apart depending upon their active wavelength range. The cladding layer may include two or more material layers of at least two different dielectric constants. In that arrangement, the PVs are further grouped such that the PVs disposed in a first one of the cladding layers has a different active wavelength range than an active wavelength range of the PVs disposed in a second cladding layer.

    Abstract: A scanning Dielectric Travelling Wave Array (DTWA) device suitable for use as a wideband, tunable, two-dimensional beamformer. The device is formed from a set of planar waveguides, elongated waveguide sections and/or progressive delay layers. By controlling the index of refraction (ε) of the waveguides, waveguide sections, and/or progressive delay layers, the device to aim at a particular angle of incidence of energy arriving on the top face, in both azimuth and elevation. These indi(cies) of refraction may be controlled with a set of varactors. By observing a constraint on the size of the waveguides as related to the bandwidth of the signals of interest, the waveguide can to receive from or transmit to different directions at the same time. The varactors may be provided by continuous strips of material disposed along the top and bottom of each waveguide section, or as a set of discrete controllable sections distributed along the primary axis of each waveguide section. Pairs of adjacent waveguide sections may be fed to provide complementary propagation modes, such as TE1 and TM1 modes. The pair of waveguide sections may be driven in quadrature to provide greater control over the axial ratio.
