Sum rules and physical bounds for a particulate slab --- transmission
Two different sum rules for transmission of the coherent electromagnetic field by a particulate slab are established. The particles are assumed spherical and randomly located, and the slab is illuminated by a plane wave at normal incidence. These sum rules are obtained assuming the particles are passive scatterers, and satisfy energy conservation and causality conditions. The sum rules are then emTwo different sum rules for transmission of the coherent electromagnetic fieldby a particulate slab are established.
