“Percolation” of acoustic wave in acoustic waveguide composed of two zero-index mediums
The transmission property of acoustic wave in a waveguide composed of index-near-zero (INZ) and reciprocal-modulus-near-zero (RMNZ) has been investigated. As long as the connectivity of the INZ is not broken, the transmittance of acoustic wave in the waveguide is kept close to 100%, which is unaffec...
