Summary: 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. A formula for the resonance close to the eigenvalue of the internal operator is obtained.
