Electromagnetic Wave Scattering by Small Impedance Particles of an Arbitrary Shape [PDF]
Scattering of electromagnetic (EM) waves by one and many small ($ka\ll 1$) impedance particles $D_m$ of an arbitrary shape, embedded in a homogeneous medium, is studied. Analytic formula for the field, scattered by one particle, is derived. The scattered

Using a Parallel Helical Sensing Cable for the Distributed Measurement of Ground Deformation
Surface and underground stretched deformation is one of the most important physical measurement quantities for geological-disaster monitoring. In this study, a parallel helical sensing cable (PHSC) based on the time–domain reflectometry (TDR ...

Modeled channel distributions explain extracellular recordings from cultured neurons sealed to microelectrodes [PDF]
Amplitudes and shapes of extracellular recordings from single neurons cultured on a substrate embedded microelectrode depend not only on the volume conducting properties of the neuron-electrode interface, but might also depend on the distribution of ...

Application of the surface‐charge distribution method to the interpretation of impedance measurements of a rocket‐borne dipole antenna [PDF]
In a companion paper [Béghin and Kolesnikova, this issue], we have presented the surface charge‐distribution (SCD) method for modeling a complex devices's behavior in the radio frequency range around the plasma resonance. Here we give one application of this method to the interpretation of published experimental data of a sounding rocket experiment ...
