Introduction: Improved signal-to-noise ratio (SNR) has led the drive for high magnetic field scanners. While substantial progress has been made toward exploiting high field benefits for head imaging, high field torso imaging has been hindered by non-uniform B1+ distribution and inadequate B1+ in the center of the torso. Stripline coils have become the preferred method for RF excitation at 7T du...

We have developed a stripline-based microfluidic device for on-chip microscale nuclear magnetic resonance (NMR), which is characterized by performing NMR experiments on a 0.2 μl ethanol sample. This NMR stripline-based device, which has an improved mechanical stability, presents an enhanced sensitivity (3.7·10 spins/ (Hz)) and achieves a full-width-half-maximum linewidth of 2.35 Hz.

Operational principles of stripline and pill-box cavity beam position monitors (BPMs) are discussed. Their theoretically best achievable position and time resolutions are computed. Numbers are estimated using design values of the proposed e+e− linear collider TESLA. Introduction Important characteristics of a beam position monitor (BPM) are position and time resolutions. Position resolution is ...

Bandpass filters (BPF) may be constructed by cascading lowpass (LP) and highpass (HP) filters. This type of realization is suitable for devices with wide bandwidths but is not convenient for the realization of narrowband BPFs, that is, for bandwidths of less than about 10 percent [1]. This is related to the high degree (number of poles and zeros) needed for the filters to achieve good selectivi...

Fast resonance frequency modulation of a superconducting stripline resonator is investigated. The experiments are performed using a novel device which integrates a hot electron detector (HED) into a superconducting stripline ring resonator. Frequency modulation is demonstrated by both applying dc current or voltage to the HED, and by applying optical illumination, with modulation frequencies of...

In this paper, we introduce a new method: support vector regression (SVR) method to modeling low temperature co-fired ceramic (LTCC) multilayer interconnect. SVR bases on structural risk minimization (SRM) principle, which leads to good generalization ability. A LTCC based stripline-to-stripline interconnect used as example to verify the proposed method. Experiment results show that the develop...

We present a method to measure the absolute surface resistance of conductive samples at a set of GHz frequencies with superconducting lead stripline resonators at temperatures 1-6 K. The stripline structure can easily be applied for bulk samples and allows direct calculation of the surface resistance without the requirement of additional calibration measurements or sample reference points. We f...
