摘要： A device may include a first antenna and a second antenna. The device may further include a frequency domain multiplexer configured for receiving a first input signal. The frequency domain multiplexer may have a first output port connected to the first antenna and configured for supplying a signal in a low band frequency range of the first input signal to the first antenna, and a second output port connected to the second antenna and configured for supplying a signal in a high band frequency range of the first input signal to the second antenna. The device may also include a third antenna configured for receiving a signal in a mid band frequency range of a second input signal. The low band frequency range may be separated from the high band frequency range.

摘要： Before submitting a sample, including a first material layered upon a substrate, to an ion milling process, whereby a second material is sputtered onto the surface of the first material and the sample is then submitted to an etching process, an irregularity is formed on the surface of the first material. The overall process results in the formation of cones, or micro-tip structures, which may then be layered with a layer of low work function material, such as amorphous diamond. The irregularity in the surface of the first material may be formed by polishing, sandblasting, photolithography, or mechanical means such as scratching.

摘要： A system and method is available for fabricating a field emitter device, where in an emitter material, such as copper, is deposited over a resistive layer which has been deposited upon a substrate. Two ion beam sources are utilized. The first ion beam source is directed at a target material, such as molybdenum, for sputtering molybdenum onto the emitter material.
