TLDR
In this article, a cross-type antenna feed (10, 30, 70, 78, 94, 94) was proposed for linear or circularly polarised systems with a reflector antenna in addition or in a low noise block (LNB) receiver.Abstract:
The present invention relates to antenna feeds (10, 30, 70, 78, 94) for use in linear or circularly polarised systems. In one embodiment of the invention, a cross-type antenna feed (30) comprises a cylindrical metal waveguide housing (12) and a cross-type metal feed body (32) coupled to the front of the waveguide housing (12). The feed body (32) has four peripherally spaced corrugated arm portions (34) arranged in a mutually orthogonal relationship, where the arm portions (34) extend radially outwardly from a longitudinal axis (16) of the feed body (32). Ridges (36) on each arm portion (34) are arranged concentrically around the axis (16) and parallel thereto, with successive ridges spaced from the axis (16) in a tiered arrangement. In another embodiment the antenna feed is a dielectric lens. The antenna feed is used in an antenna system having a reflector antenna in addition or in a low noise block (LNB) receiver.read more

Methods for targeted electrosurgery on contained herniated discs
TL;DR: In this paper, an electrosurgical probe is guided to a specific target site within a disc to be treated, and the disc tissue at the target site is ablated by application of at least a first high frequency voltage between the active electrode(s) and one or more return electrodes(s), wherein the volume of the nucleus pulposus is decreased, pressure exerted by the nucleus on the annulus fibrosus is reduced, and discogenic pain of a patient is alleviated.
