Experimental investigation of near-field effects on the SASW dispersion curve
… inversion procedure that is used to analyze the field dispersion curve to determine the field V[subscript s] profile, the analysis is based on the wave field consisting of plane Rayleigh waves. Therefore, field dispersion curves that contain near-field data could adversely distort the field …

Investigation of nanoscale thermal radiation : theory and experiments
… or macroscopic radiative energy transport - wave effects, such as interference and diffraction, and near-field effects play a significant role. By modeling thermal radiation as governed by Maxwell's equations and relating the source of thermal radiation to temperature induced fluctuations of …

Structural energy and power flow using a scanning laser Doppler vibrometer
… the continuous 3-D complex-valued velocity field is solved from the laser data. Third, a spatially continuous model of the power is computed from the velocity-field model obtained in stage 2. The results of the ESPF method were validated by using both simulated and experimental laser data. …

Multistation Methods for Geotechnical Characterization using Surface Waves
… of the properties of Rayleigh waves in layered linear elastic and linear viscoelastic media is presented, together with their applications for site characterization, of whose the SASW (Spectral Analysis of Surface Waves) method is by far the most well-known in geotechnical engineering. The …

An Information-Theoretic Examination of Next Generation Location Systems: The Role of LEOs, RISs and the Near Field
… reconfigurable intelligent surfaces (RISs), and near-field propagation—to enhance localization accuracy and resilience. LEO satellites, originally designed for communication, have recently seen widespread deployment through constellations such as Starlink, OneWeb, and Kuiper. Their growing …

Ultra-low frequency wireless transmitter design using resonant oscillating permanent magnets
… has been achieved using a quasi-static magnetic field generated by electromagnetic coils that are few meters in length. Nevertheless, if these coils are scaled down to be made man-portable, they require large input power even to generate a magnetic field that can be detected over a few meters. In …
