Switched-beam endfire planar array with integrated 2-D Butler matrix for 60 GHz chip-to-chip spacesurface wave communications," IEEE Antennas Wireless Propag.

Thin film nanostructured photovoltaic cells are increasing in efficiency and decreasing the cost of solar energy. FDTD modeling of branched nanowire 'forests' are shown to have improved optical absorption in the visible and near-IR spectra over nanowire arrays alone, with a factor of 5 enhancement available at 1000 nm. Alternate BNW tree configurations are presented, achieving a maximum absorption of over 95% at 500 nm.
