A method for generating an electron beam includes prescribing a location, and generating an envelope of electrons, the envelope having a waist, wherein the generating is performed such that the waist of the envelope is at or adjacent to the prescribed location. A device for generating an electron beam includes a gun source for generating electrons, and a plurality of electromagnetic cavities coupled in series to form a body, the electromagnetic cavities configured to accelerate at least some of the electrons to create a beam of electrons at an energy level having a value between 5 MeV and 20 MeV, the beam of electrons having a cross sectional dimension that is 0.02 &#x3bb; (or 2 mm) or less.

An omni-directional antenna assembly is provided for wireless communication devices requiring multiple polarization characteristics. A loop antenna assembly for a communications device operating at a predetermined wavelength and having a transceiver circuit including a signal output and a ground plane, the antenna assembly including a conductive loop element and a conductive leg member coupled to the loop element proximate a loop perimeter, the leg member for supporting the loop element at a distance away from the ground plane of the communications device, the leg member also defining a ground point and a feed point for operatively coupling the loop element to the ground plane and the signal output, respectively, of the transceiver circuit.
