WebAn extended optical theorem was presented for non-diffracting acoustic beams. 6. and later extended to electromagnetic scattering. 7. In this letter, a generalized optical theorem applicable to an arbitrarily shaped incident wave is derived and presented for the time-harmonic (single-frequency) scatter-ing. Webconsequence of this rather abstract property, derived the generalized optical theorem [5]. Back in electromagnetic theory, H.C. van de Hulst rediscovered the optical theorem in 1949 [6], unaware that it was already well known both in optics and in quantum scattering theory. The optics
WebMar 22, 2012 · The generalized optical theorem as originally formulated in is an extension of the previous theorem and it deals with the scattering amplitude in all the directions; hence, it contains the ordinary form as a special case. This theorem relates the difference of two scattering amplitudes to an inner product of two other scattering amplitudes.
