Impedance matching law is a key problem in the development of electromagnetic absorbing material.Base on interaction between electromagnetic wave and material,the impedance formula is obtained when electromagnetic wave transmit through the material.It follows that an impedance matching condition without surface reflection when incident electromagnetic wave is given.And furthermore,the correctness and applicability are validated by electromagnetic numeric calculus.This matching condition has specific physic significance,and the formula is simple,transparent and advantageous to develop high efficient electromagnetic absorbing material.
