... effect of the acoustic cloak, it is found that the incident sound wave can pass through the acoustic cloak smoothly with the less backscattering TS using an appropriate δ value. More importantly, it is seen that the essential requirement for the infinite mass density in Cummer's acoustic cloak can...

... for one dimensional column (Simon et ai, 1984) and that too for compatible properties of the mass density and bulk moduli of solid and fluid. Al- though presented in closed form, these solutions contain expressions which must be evaluated numerically using a digital computer. The finite element method has...
