The ability to acoustically cloak an object, effectively making the object acoustically invisible
to an outside observer, is of interest in many applications where the presence of an object …

We consider the problem of how to cloak objects from antiplane elastic waves using two
alternative techniques. The first is the use of a layered metamaterial in the spirit of the work …

Using a sum rule, we derive new bounds on Herglotz functions that generalize those given
in Bernland et al.[J. Phys. A: Math. Theor. 44 (14), 145205 (2011)] and Gustafsson and …

We present a new method to create an active cloak for a single clamped inclusion in a
Kirchhoff plate in the presence of flexural waves. In order to cloak this inclusion, we place …

An active elastodynamic cloak destructively interferes with an incident time harmonic in-
plane (coupled compressional/shear) elastic wave to produce zero total elastic field over a …

The research performed in this paper suggests that the radar cross section of an arbitrarily
shaped object can be reduced by canceling the scattering from the object with the radiation …

Active noise cloaking of rigid and elastic 2D cylindrical shells in an infinite acoustic medium
is presented. The control approach utilises control sources or forces and discrete error …

The vibro-acoustic response of a two-dimensional cylindrical shell in low Mach number flow
is herein derived. The analytical model takes into account the structural elasticity and …

An active cloak consists of a set of discrete multipole sources distributed in space. When the
source positions and amplitudes are carefully specified the active field destructively …

We derive a formula for the gradients of the total scattering cross-section (TSCS) with
respect to positions of a set of cylindrical scatterers. The analytic form enhances modeling …
