We present an active cloaking method for the parabolic heat (and mass or light diffusion) equation that can hide both objects and sources. By active we mean that it relies on designing monopole and dipole heat source distributions on the boundary of

International audience; Acoustic cloaking is the minimization of the scattered sound wave from the target object due to the action of a probing wave in order to render it acoustically invisible. Active exterior cloaking requires the use of sound sour

Active Cloaking for Finite Clusters of Pins in Kirchhoff Plates

Autor: Ö. Selsil, Richard V. Craster, S. G. Haslinger, Natalia V. Movchan, J. O'Neill

Publikováno v: SIAM Journal on Applied Mathematics. 77:1115-1135

This paper considers active cloaking of a square array of evenly spaced pins in a Kirchhoff plate in the presence of flexural waves. Active sources, modeled as ideal point sources, are represented by the nonsingular Green's function for the two-dimen
