This article investigates the design, modeling, and fabrication of small-size (150 × 90 1.6 mm) broadband printed biconical antenna. The proposed antenna is intended for use a reference electromagnetic interference measurement inside EMC chamber. reflection coefficient (S11-parameter) verified by modeling equivalent circuit structure in terms lumped elements. offers −10 dB impedance bandwidth (...

Abstract With amplitude ratio of two different types ground motion, the information phase velocity could be reflected in frequency-dependent assumption plane-wave propagation. In this paper, we test possibility determining local Love waves dispersion properties using transverse and strain measurement. seismic wave recording four-component borehole strainmeters built at Balun station Xinjiang, C...
