Weekly Seminar: “From Time-Reversal Mirrors to Tunable Metasurfaces”

Speaker: Prof. Mathias Fink

ABSTRACT: Time-reversal invariance is a very fundamental concept in physics. The objective of this talk is to show how this concept can be turned into a huge source of innovations and successful start-up companies. It was first in the field of acoustics and later for microwaves, where antenna array technology was available, that “time-reversal mirrors” [...]
