This paper discusses harvesting of low-power density incident plane waves for electronic devices in environments where it is difficult or impossible to change batteries and where the exact locations of the energy sources are not known. As the inciden

Planar rectenna arrays for rectification of broadband electromagnetic waves of arbitrary polarization are designed and characterized. The performance of the arrays is accurately predicted using a combination of full-wave analysis for the passive part

Spectral estimation and direction-of-arrival (DOA) estimation is considered for discrete lens antenna array front ends. In this approach, when using the Multiple Signal Classification (MUSIC) algorithm, the dimension is reduced by the front end which

This paper presents an approach to millimeter-wave passive ranging using a method that has been demonstrated in the visible range. Ranging is achieved for multiple objects by way of a receiving discrete lens with modulated amplitude and/or phase resp
