The effect of longitudinal waves excited by a ring aperture antenna in a plasma on the input conductance of this antenna is investigated on the b asis of a hydrodynamic plasma model. It is shown that in the low-frequency region (below the plasma frequency) the excitation of longitudinal ...

Firstly, in order to obtain the transverse/dorsoventral signal the sensor was placed horizontally between the mattress and the bed base, below the upper part of a volunteer's body, similar to the placement of most modern bed-embedded BCG sensors. The upper plate, facing the mattress, is ...
