A multi-frequency quadrature bridge

1998 Conference on Precision Electromagnetic Measurements Digest (Cat. No.98CH36254), 2002
A quadrature bridge has been developed with the aim of determining capacitance values at several frequencies in terms of a resistance ultimately derived from the QHR. The bridge is evaluated by comparing a 1 nF capacitor with a 100 k/spl Omega/ resistor at six frequencies from 3/8/spl times/10/2/spl pi/ kHz to 10/2/spl pi/ kHz.

Multi-frequency ESR in EuFe2As2

Journal of the Korean Physical Society, 2013
We have performed multi-frequency electron spin resonance (ESR) measurements on EuFe2As2, which is one of the parent compounds of Fe-based superconductors. At T SDW=190 K, this compound shows a spin-density-wave (SDW) transition.

THz Multi-frequency resonance filter

2008 33rd International Conference on Infrared, Millimeter and Terahertz Waves, 2008
The transmission characteristic of a two-dimensional array of rectangular holes was examined theoretically and experimentally in the THz frequency range. The structure under consideration was found to act as a multi-frequency resonance filter whose frequency response of transmission depends on the periodicities and filling material of the structure.

Multi-frequency narrowband tissue characterization

IEEE Symposium on Ultrasonics, 2002
Characterization of the tissue of a thin layer (e.g. an artery wall) can be achieved by comparison of the spectra of the reflections from the boundaries of the tissue layer. To avoid problems that arise from the use of short (broadband) pulses, the method proposed uses long and almost monochromatic pulses.

Multi-frequency band receiver

The invention relates to a multi-frequency band receiver comprising a first receiving path, a second receiving path, a combiner, a code multiplex base band stage and an amplifier controller. The first receiving path receives and processes a first code multiplex signal and the second receiving path receives and processes a second code multiplex signal ...

Multi-Frequency Atomic Force Microscopy

2010
The atomic force microscope (AFM) was invented in 1986 [1], a close relative of another instrument, the scanning tunneling microscope (STM), invented in 1981 [2]. Both fall under the umbrella of techniques and instruments referred to as scanning probe microscopes (SPMs), with the common thread being that a sharp probe is scanned in a regular pattern to
