Abstract
We analyze the influence of thermal disordering of meta-atoms on the electromagnetic properties of liquid metacrystals (LMCs) composed of ellipsoidal plasmonic nanoparticles suspended in viscous liquid. Within the kinetic approach we find the temperature dependence of the components of the LMC permittivity tensor. We show that thermal transitions between dispersion states with different topologies of isofrequency surface are possible. We also study the impact of thermal fluctuations on the optical nonlinearity of LMC.
