How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
We propose a method of applying a static magnetic field to reduce the attenuation of the magnetic field component (SH) of low-frequency electromagnetic (LF EM) waves in dense plasma. The principle of this method is to apply a static magnetic field to limit electron movement, thereby increasing the equivalent resistance and thus reducing the induced...
In this paper, a fast and efficient defect location system utilizing compressive sensing is proposed for detecting defects in solar cells. It measures the total output of the sample solar cell under excitation of patterns displayed by a liquid crystal display. Then the defects are located compressively by solving a convex problem using a small numb...
For the low level current preamplifier circuits in photo-electric detection, the bandwidth and the low noise characteristics are usually contradictory, because the bandwidth is limited by the high value resistor and its inevitable parasitic capacitances, which together exhibit low-pass characteristics. To expand the bandwidth of low level current a...
