Measurement Techniques, USA. 2020. № 10. С. 54–59.
A computer model and the results of a numerical experiment for a sensitive element on a planar mushroom-shaped metamaterial with cells of the "Maltese cross" type are presented. The proposed electrodynamic structure is shown to be applicable for non-destructive testing of geometric and electrophysical parameters of technological media, as well as searching for inhomogeneities in them. Resonant frequency shift and change of the attenuation coefficient value of the structure serve as informative parameters.

This paper presents a software tool developed for processing terahertz thermal images of the human face acquired during a controlled psychophysiological experiment. In the experiment, a 500 GHz single-pixel detector combined with a two-mirror scanning system forms a sequence of low-resolution thermal frames (700×51 pixels) of the subject’s face while the person undergoes relaxation and ...

The key principle of the operation of an unmanned aerial vehicle is the
continuous collection and processing of data from on-board sensors, controlled by a
real-time operating system (RTOS). For multicopters, where the minimum delay in
the system’s response to changes in flight is critically important, the main factor is the
performance of the flight controller’s computing core. Historically, ...

Superconducting properties of metallic micro- and nanowires can be entirely different from those of bulk superconductors. Of particular interest is the nonequilibrium current-induced state of a quasi-one-dimensional superconducting channel. The most interesting phenomenon here is the stepped I–V characteristic, explained by a process known as phase slip center activation. If the origin of such step-like ...
