Metasurfaces are artificial array structures consisting of subwavelength unit cells arranged on a specific two-dimensional surface. Dynamic, reconfigurable metasurfaces are an excellent way to ...
A time domain reflectometer (TDR) measures reflections along a cable. It is similar in principle to radar. To measure those reflections, the TDR transmits an incident signal into the cable and watches ...
Time reflections, or spatial reflections, occur when "electromagnetic radiation in the form of light or sound waves hit a mirror or wall, respectively," resulting in a reflection, like a mirror image ...
