Materials are known to interact with electromagnetic fields in different ways, which reflect their structures and underlying properties. The Lyddane-Sachs-Teller relation is a physics construct that describes the relationship between a material's static and dynamic dielectric constant (i.e., values indicating a system's behavior in the presence or absence of an external electric field, respectively) and the vibrational modes of the material's crystal lattice (i.e., resonance frequencies).
