Comment on "Design of acoustic devices with isotropic material via conformal transformation" [Appl. Phys. Lett. 97, 044101 (2010)]
Andrew N. Norris

The paper presents incorrect formulas for the density and bulk modulus under a conformal transformation of coordinates. The fault lies with an improper assumption of constant acoustic impedance.
