Core Disking Phenomenon on the Compact Conical-ended Borehole Overcoring(CCBO) Technique.

Electromagnetic logging technique based on borehole radar

An electromagnetic logging technique based on borehole radar is introduced in this paper. The tool consists of one transmitter and two receivers, which can be used to cancel the effect of the antenna characteristics by taking the ratio of two receiver signals. Since receiver signals measured in the time domain can be converted into the frequency domain by Fourier transformation, the amplitude r...

Investigating the RoCos Core Spun Compact Yarn Properties

A Wideband Compact Planar Conical Loop Antenna

This paper reports the design of a wide band planar fed, planar conical loop Antenna. Parametric studies have been carried out to arrive at the optimum antenna dimensions to have a wide impedance bandwidth (VSWR<2). Experimental results confirmed the wide impedance bandwidth.

Modeling the Properties of Core-Compact Spun Yarn Using Artificial Neural Network

Interferometric characterization of the structured polarized light beam produced by the conical refraction phenomenon.

The interest on the conical refraction (CR) phenomenon in biaxial crystals has revived in the last years due to its prospective for generating structured polarized light beams, i.e. vector beams. While the intensity and the polarization structure of the CR beams are well known, an accurate experimental study of their phase structure has not been yet carried out. We investigate the phase structu...
