摘要: An electromagnetic wave is transmitted from and received by an antenna system (300) having a cavity member (310), a passive antenna element (320) and a driver element (330). The cavity member has a back portion (311) and a wall portion (312) which define a substantially cylindrical interior portion. The passive antenna element has a first end (321) disposed within the interior portion of the cavity member. The driver element is coupled to the interior portion of the cavity member.

摘要: An axial field electric machine (10) having an improved efficiency comprising a number of magnetic elements, e.g., rotor (14) as annular disks magnetized to provide multiple sector-shaped poles (58). The poles (58) of each disk (14) are aligned with opposite poles of each adjacent magnet (60). The axial field electric machine (10) further includes one or more conductor elements, e.g., stator (12) which include a number of conductor phases (110) that traverse the flux emanating between poles of axially adjacent magnetic elements.
