Estimation of the Highest Influence on the Measured Results of a Three-axis Shielded Loop Antenna Using Three Transmitting Antenna and Tilted Antenna Methods

Autor: Denys Pokotilov, Robert Vogt-Ardatjew, Frank Leferink

Publikováno v: 2022 International Symposium on Electromagnetic Compatibility – EMC Europe, 237-241
STARTPAGE=237;ENDPAGE=241;TITLE=2022 International Symposium on Electromagnetic Compatibility – EMC Europe

Low-frequency radiated EMI measurements around equipment under test are typically based on the measurement of the magnetic field components with a shielded loop antenna. The number of measurement positions, antenna orientations, and different types o

Combined effects of permeability and ﬂuid saturation on seismic wave dispersion and attenuation in partially-saturated sandstone

Autor: Qianqian Wei, Min Sun, Qi Huang, De-hua Han, Yang Wang

Publikováno v: Advances in Geo-Energy Research, Vol 5, Iss 2, Pp 181-190 (2021)

Knowledge of dispersion and attenuation is essential for better reservoir characterization and hydrocarbon identiﬁcation. However, limited by reliable laboratory data at seismic frequency bands, the roles of rock and ﬂuid properties in inducing d
