Question: An object scatters an incident plane wave with E inc (r, t) = e 0 E 0 exp[i(k 0 r t)]. Use the

An object scatters an incident plane wave with Einc(r, t) = ê0Eexp[i(k· r − ωt)]. Use the Maxwell stress tensor formalism to show that the time-averaged force on the object can be written in terms of the incident wave intensity Iinc, the total cross

 section σtot, and the differential cross section for scattering dσscatt/dΩ as

linc do scatt (F) 1 = Live [auko- f 152+d] [ dQ

The projection of this force on the direction k̂is often called the radiation pressure due to scattering.

linc do scatt (F) 1 = Live [auko- f 152+d] [ dQ f "]. tot C
