Model of Point-Like Window for Electromagnetic Helmholtz ResonatorIgor Yu. Popov (1) St. Petersburg National Research University of Information Technologies, Mechanics and Optics, Russian Federation
Point-like interaction between internal and external operators as a model of electromagnetic Helmholtz resonator is suggested. It is based on the theory of self-adjoint extensions of symmetric operators in Pontryagin space. Formula for the resonance close to the eigenvalue of the internal operator is obtained.
Keywords: Operator extensions theory, singular perturbation, Maxwell operator, Pontryagin space
