In this paper, we develop a topology optimization to control thermal waves which allow wave-like profile of temperature by conduction and convection. To calculate the convection velocity for low Reynolds flow in porous media, the Darcy law and the pressure equation are solved, and the thermal wave is analyzed by the finite element method assuming the temperature of harmonic wave in the advection-diffusion equation. The structure for cloaking the temperature distribution of the thermal wave disturbed by obstacles is designed by topology optimization, and the level set function representing the structure is optimized by the covariance matrix adaptation evolution strategy (CMA-ES).
