We study a configuration for displacement detection consisting of a nanomechanical resonator coupled to both a radio frequency superconducting interference device and to a superconducting stripline resonator. We employ an adiabatic approximation and rotating wave approximation and calculate the displacement sensitivity. We study the performance of such a displacement detector when the stripline...

Recent developments in micromachining techniques at the University of Michigan have resulted in novel high-performance low-loss filters for microwave and millimeter-wave applications. The idea is based on suspending the filters on thin dielectric membranes to eliminate dielectric loss and dispersion problems, resulting in a pure TEM mode of propagation and conductor-loss-limited performance. Th...

A planar triple-band monopole antenna with a U-shaped stripline and a L slot is presented. The antenna is very compact with a size of 20 × 30 × 1.5mm3 and fed by a 50 Ω microstrip line with a defected ground. The measured −10 dB impedance bandwidth of the proposed antenna covers 2.33 GHz–2.51GHz, 3.25 GHz–3.82 GHz, and 4.83 GHz–8.4GHz, respectively, which meets the specifications of WLAN 2.4/5....

In this study, a high-performance, dual linearly polarized patch array antenna is presented for satellite synthetic aperture radar (SAR) applications. The features an aperture-fed stacked as the radiation element and stripline feeding network. A high-performance low-loss dielectric substrate RF-35 by Taconic, honeycomb used. used to maximize impedance bandwidth decrease insertion loss of antenn...

The beam position monitor (BPM) system for the SPring-8 linac is composed of BPMs, signal processors, VME computers for data acquisition, an external trigger system, and their connections. The BPM is a four-channel electrostatic stripline monitor whose stripline length is 27 mm. The BPM outputs a pure 2.856 GHz sinusoidal wave. For a single bunch beam, a band pass filter whose bandwidth is 10 M...

The Brookhaven Accelerator Test Facility (ATF) is a dedicated user facility for accelerator physicists. Its design is optimized to explore laser acceleration and coherent radiation production. To characterize the lowemittance, picoseconds long electron beam produced by the ATF's photocathode RF gun, we have installed electron beam profile monitors for transverse emittance measurement, and devel...

The comparison of simultaneous humidity measurements by the Vaisala RS92 radiosonde and by the Cryogenic Frostpoint Hygrometer (CFH) launched at Alajuela, Costa Rica, during July 2005 reveals a large solar radiation dry bias of the Vaisala RS92 humidity sensor and a minor temperature-dependent calibration error. For soundings launched at solar zenith angles between 10° and 30°, the average dry ...
