Active exterior cloaking for the 2D Helmholtz equation with complex wavenumbers and application to thermal cloaking
Maxence Cassier, Trent DeGiovanni, Sébastien Guenneau +1
We design sources for the two-dimensional Helmholtz equation that can cloak an object by cancelling out the incident field in a region, without the sources completely surrounding t…
