Transformation optics has shaped up a revolutionary electromagnetic design paradigm, enabling scientists
to build astonishing devices such as invisibility cloaks. Unfortunately, the application of transformation
techniques ...
A recently proposed analogue transformation method has allowed the extension of transformation acoustics to general space-time transformations. We analyze here in detail the differences between this new analogue transformation ...

We apply a homogenization process to the acoustic velocity potential wave equation. The study of various
examples shows that the resulting effective properties are different from those of the homogenized pressure
wave ...
