We theoretically propose a scheme to realize the dynamic control of the properties of the terahertz（THz） rainbow trapping effect（RTE） based on a silicon-filled graded grating（SFGG） in a relatively broad band via optical pumping.Through the theoretical analysis and finite-element method simulations,...
