    摘要： A micro etching system using laser ablation includes a laser generator, an optical fiber waveguide, a laser beam focusing device and a sample platform. The laser generator generates an ultraviolet beam, and the optical fiber waveguide carries the laser beam radiated from the laser generator to the material to be etched. The focusing device is provided between the laser generator and optical fiber waveguide and serves to concentrate the laser beam into the optical fiber. The sample platform controls the position of the material to be etched so that the material is etched at a predetermined angle by the beam emitted from the outlet of the optical fiber waveguide.

    摘要： A coaxial connector for microwave and millimeter wave measurement can be used by attachment to a vacuum chamber for instrumentation when measuring a high frequency characteristic for various electronic devices at low temperature. The coaxial connector connects microwave instrumenting equipment to a device to be tested within vacuum chamber (e.g., so as to measure a low temperature and high frequency characteristic for a high frequency device). It includes a support plate for attachment to the vacuum chamber and a support screw to prevent the coaxial connector from rotating. The support screw is of hexagonal shape in the exemplary embodiment and is arranged to one side on the center of the support plate. A coaxial cable transmits the measured signal and is extended to pass through the center of the support plate and support screw, and a V-shape connector on each end of the cable for respectively coupling between a fixed sample stand in the vacuum chamber and the microwave instrument equipment.

Radio frequency (RF) chokes and quarter wavelength radial-stubs are connected between the electrodes and the microstrip transmission line in order to prevent high frequency signals from flowing into a DC bias terminal. A plurality of PBGS are periodically arrayed on a ground plane of the substrate.
