The Dipole Resonator and Dipole Waveguide Insulator in Dense Liquid Medium

In this paper, the propagation of sound in an acoustically narrow waveguide, wall which is lined with identical dipole resonators and masses on springs, theoretically considered. It shown that, frequency range above resonant resonators, waves exponentially attenuate, waveguide locked. The width depends two parameters—the ratio cross-sectional areas mass resonator to medium displaced by it. As decreases, locking band expands may become infinite.
