?erenkov-based radiation from superluminal excitation in microdroplets by ultrashort pulses.
We demonstrate from a generalized Lorenz-Mie theory that ultrashort pulses can induce superluminal excitation in microdroplets. A ?erenkov-like effect can thus be expected for sufficiently intense ultrashort pulses.
