“…This can explain why the Kirchhoff approximation is valid only when d x is large with respect to the wavelength [4]. The same result can be obtained for 1D gratings in the p polarization case.…”

“…The main advantage of the classical physical optics approximation lies in its simplicity, which entails a straightforward numerical treatment and a short computation time. On the other hand, it has been shown that this method may fail in resonance conditions, when the wavelength of the incident field has the same order of magnitude as the dimensions of the diffracting object [4]. Due to this reason the variation of the section of the nearly 2D object on two planes orthogonal to the privileged axis and separated by one wavelength must be small with respect to the wavelength.…”

We study light scattering and absorption in thin film solar cells, using a model system of a sinusoidally textured silver reflector and dielectric layers of ZnO and amorphous silicon. Experimental results are compared to a theoretical model based on a Rayleigh expansion. Taking into account the explicit interface profile, the expansion converges fast and can be truncated typically after three or four orders. At the same time, the use of realistic permittivity data correctly reproduces the intensity of diffracted orders as well as the coupling to guided modes and surface plasmon polariton resonances at the silver surface. The coupling phenomena behind the light trapping process can therefore be assessed in a simple, yet accurate manner. V C 2012 American Institute of Physics. [http://dx

“…In the low frequency limit, a rough surface scattering problem can be solved with the help of the small perturbation method. Up to first order in a, it is shown that the scattering amplitude at infinity can be expressed in terms of the Fourier transform of the profile [ 15]. Indeed, denoting by a and a' the x components of the wave-vectors of the incident and scattered plane waves, respectively, the scattering amplitude r( a, a') writes …”
