Abstract: An antenna with multiple feeds of single polarization comprises an array of multiple antenna elements. An antenna assembly comprises a radiation unit, multiple RF feeding locations and a waveguiding structure configured to control the amplitude and phase of feeding signals that are directed to the feeding locations for achieving defined radiation beam shape and radiation bandwidth. The waveguiding structure is adapted to provide the RF signals to the multiple feeding locations in one of a single polarization and a linear polarization.

Abstract: A system for identifying and optionally treating biological material is provided. The system includes a coherent light source for irradiating the biological material and device for collecting light waves reflected from the biological material and transforming the light waves to nanoplasmonic waves. The system also includes a processing module for extracting phase and amplitude information from the nanoplasmonic waves to identify the biological material based on the phase and amplitude information.

Abstract: A non-occlusive intravascular device for local application of a therapeutic agent to a selected segment of a lumenal wall of a blood vessel without applying radial force on the wall. The device comprises a radially expandable/collapsible flexible scaffold of an open-skeletal structure and a flexible outer surface capable of conforming to the lumenal wall without applying radial force thereon and a controllable mechanism for expanding and collapsing the scaffold. The therapeutic agent is loaded and carried on the outer surface of the scaffold. Also provided are a method and a system for delivering a therapeutic agent to a selected segment within a blood vessel.

Abstract: An apparatus for feeding an antenna array may include a first layer including one or more antennas; a second layer adapted to convey an electromagnetic wave; and an aperture in a wall of the second layer enabling the electromagnetic wave to reach the first layer.

Abstract: The presently disclosed subject matter includes an electromagnetic seeker comprising: an antenna having multiple radiating elements; the antenna is divided into a plurality of sections, each section comprising a group of radiating elements and is directly connected to a respective single power stage configured to provide power to the radiating elements; each section and a respective single power stage are configured to provide a coherent combination of signals transmitted by different antenna sections over the air to thereby enable combination of power from all antenna sections over the air.
