The invention discloses a wave-absorbing characteristic regulation and control method for regulating and controlling local strain of a flexible metamaterial film, which comprises the following steps of superposing or folding a plurality of layers of flexible electromagnetic wave-absorbing metamaterial films into a preset shape, and forming the key size of a metamaterial structure unit in an arrayorganization mode through heating regulation and control, namely, the key size can be used for broadband electromagnetism. The heating power and the temperature rising speed are controlled through theelectric power, and the key size of the metamaterial structure unit on the thermal shrinkage film is adjusted by utilizing the electric heating temperature rising, so that the regulation and the control on the wave absorbing characteristic peak value and the wave absorbing main frequency band of the flexible metamaterial film are realized. Or the energy of the high-power light source can be transmitted to a key part which
