From: Analytical realization of complex thermal meta-devices
A Illustration of thermal rotator: heat flux in the core is rotated by a specified angle without perturbing the background’s heat flux distribution; B thermal rotators obtained with various specified rotation angles and their Vio-index values and Relative Angular Difference (RAD) values under Y- and X-direction applied heat (RAD-Y and RAD-X); C, D temperature and heat flux distributions of the 45-degree thermal rotator (FE simulation) under Y- and X-direction applied heat flux; E Illustration of thermal concentrator: heat flux in the core is magnified by a specified concentration level without perturbing the background’s heat flux distribution; F thermal concentrators obtained with various specified concentration levels and their Vio-index values and Relative Gradient Difference (RGD) values under Y- and X-direction applied heat (RGD-Y and RGD-X); G, H temperature and heat flux distributions of the 1.8-concentration level thermal concentrator (FE simulation) under Y- and X-direction applied heat flux.
