“…We start considering the cloaking problem under stationary condition (2.8)–(2.9). The steady-state OCP is solved using the Matlab function , once all the FEM matrices have been built through the library [36]. The maximum length of the sides of the triangles in the triangulation is hmax=0.1232 for a number of elements equal to 2320.…”

In this paper, we describe a numerical framework for achieving passive thermal cloaking of arbitrary shapes in both static and transient regimes. The design strategy is cast as the solution of an optimal control problem (OCP) for the heat equation where the coefficients of the thermal diffusivity matrix take the role of control functions, and the distance between the uncloaked and the cloaked field is minimized in a suitable observation domain. The control actions enter bilinearly in the heat equation, thus making the resulting OCP nonlinear, and its analysis non-trivial. We show that optimal diffusivity coefficients exist both for the static and the transient case; we derive a system of first-order necessary optimality conditions; finally, we carry out their numerical approximation using the finite-element method. A series of numerical test cases assess the capability of our strategy to tackle passive thermal cloaking of arbitrarily complex two-dimensional objects.

“…Both the HF and LF models are constructed through the numerical approximation of (7) using the MATLAB library redbKIT [47], which exploits finite elements and the backward differentiation formula for the spatial and temporal discretizations, respectively. The two fidelity levels are distinguished by the mesh and time step sizes.…”
