In this paper we demonstrate a new class of anisotropic 1D hyperbolic metamaterials (HMMs) possessing multiresonant dispersion characteristics. With the help of an EMT-based model, we analyze HMMs with unit cells composed of layers characterized by various plasma frequencies, revealing multiple resonance transitions corresponding to the critical absorptions points. In particular, we show that relative locations of plasma frequencies of constituent materials and the unit cell’s geometry determine the type of dispersion characteristics as well as spectral locations of critical absorption points. It is shown that a multispectral low-loss highly dispersive medium is achieved in a structure comprising layers of closely located plasma resonances. Moreover, we present that pure metallic multilayer structure can exhibit hyperbolic dispersion. The obtained results possess a significant potential in applications where a multispectral character is required, including phase matching, multiple-point perfect absorption, as well as diffractionless imaging and focusing.
