Method for calculating Cassimir-Polder force between two-energy-level atom and hyperbolic metamaterial plate

The invention discloses a method for calculating Cassimir-Polder force between a two-energy-level atom and a hyperbolic metamaterial plate. The method comprises the following steps: S11, establishinga two-energy-level atom and hyperbolic metamaterial plate model; S12, determining the electromagnetic characteristics of a hyperbolic metamaterial plate according to the established model; S13, calculating an electric field evolved along with time of an anisotropic medium in the hyperbolic metamaterial plate; S14, calculating frequency shift under atom internal dynamics according to the obtained electric field; and S15, according to the obtained frequency shift, calculating Cassimir-Polder force of the two-energy-level atoms and hyperbolic metamaterial plate model. According to the method, thechange of Cassimir-Polder force borne by atoms can be analyzed when the resonance frequencies of two-energy-level atoms in an excited state are located in a hyperbolic frequency band and a non-hyperbolic frequency band respec
