摘要： A high-sensitivity Pd/InP hydrogen sensor was made by a) forming an n-type or p-type semiconductor film on a semiconductor substrate; b) forming a patterned first metal electrode on the semiconductor film, wherein the first metal electrode forms an Ohmic contact with the semiconductor film; and c) forming a second metal electrode on the semiconductor film, the second metal electrode being isolated from the first metal electrode, wherein the second metal electrode forms a Schottky contact with the semiconductor film, wherein a thickness of the second metal electrode and a material of which the second metal electrode is made enable a Schottky barrier height of the Schottky contact to decrease when hydrogen contacts the second metal electrode. The second metal electrode can be physical vapor deposited or electroless plated.

摘要： An orthomode transducer includes a first waveguide section, a second waveguide section coupled to the first waveguide section, and a third waveguide section coupled to the first and second waveguide sections. The first waveguide section is configured to support the propagation of a signal having a first polarization, and includes a first waveguide aperture sized to communicate the signal having the first polarization therethrough. The second waveguide is configured to support the propagation of a signal having a second polarization which is orthogonal to the first polarization, the second waveguide section having a single internal septum and a second waveguide aperture sized to communicate the signal having the second polarization therethrough. The third waveguide is configured to support the propagation of either a signal having the first polarization or the second polarization, and includes a third waveguide aperture sized to communicate the signals having either the first or second polarization therethrough.

摘要： A parabolic rectangular horn antenna includes a source aperture, a parabolic reflector, and an output aperture. The source aperture has a first port for receiving a planar wavefront signal and a second port for providing a substantially cylindrical wavefront signal. The parabolic reflector is positioned within the horn to receive the cylindrical wavefront signal, transforming it to a substantially planar wavefront signal at a predefined location. The output aperture is positioned at the predefined location and outputs the substantially planar wavefront signal. Corrugations are adjacently placed at both sides of the output aperture to optimize the antenna beam pattern.
