摘要：
Local resonances of inhomogeneous waves in extended structures are investigated theoretically. Local resonances having an infinite Q are obtained in flexurally vibrating infinite and semiinfinite beams and plates with lumped reactive inhomogeneities. It is shown that an edge resonance occurs at any frequency at the end of a semiinfinite elastic layer with distributed reactive loads. The investigated results are based on specially formulated impedance characteristics (normal impedances).
