An electromagnetic susceptor for chemical processing that is made from a matrix material that surrounds a non-matrix material that is made from a material that is different from the matrix material, the matrix material is constructed of material having lower dielectric losses compared to the non-matrix material, the non-matrix material initially absorbs electromagnetic energy applied to the electromagnetic susceptor to a greater extent than the matrix material, the non-matrix material produces subsequent heat in the matrix material, and the greatest length of measurement of the electromagnetic susceptor is between one nanometer and 10 meters.
