原始语种摘要: The Maxwell system in a bounded domain $ \Omega (\varepsilon )$ with finitely many cavities is considered. The cavity diameters are proportional to a small parameter $ \varepsilon $. The perfect conductivity conditions are given on the boundary $ \partial \Omega (\varepsilon )$. The asymptotics of the eigenvalues $ \lambda (\varepsilon )$ is described as $ \varepsilon \to 0$. The proposed model describes the perturbations of the eigenfrequencies of an electromagnetic resonator caused by the presence of metal particles in its volume; the model can be of use for plasma diagnostics.
