Abstract

Predstavljena je osnovna kontinuumska fizika delovanja akustične metatekočine. Rešen je problem lastnih nihanj prostega diskretnega mikrooscilatorja, ki služi kot model osnovnega gradnika metatekočine. Oscilacije so nato sklopljene s splošno rešitvijo potencialnega toka v okolišnji tekočini. Predstavljena je frekvenčna odvisnost efektivne stisljivosti.

Secondary title: Acoustic metafluids with general macromolecular oscillators
Secondary abstract: The fundamental physics of an acoustic metafluid in the continuum limit is presented. The eigenvalue problem of a discrete microoscillator that serves as an elementary building block of the metafluid is solved. Oscillations are then coupled with the general solution of the potential flow in the sorrounding liquid. The frequency dependence of the effective compressibility is presented.
