D. Jiang et Jj. Stamnes, THEORETICAL AND EXPERIMENTAL RESULTS FOR 2-DIMENSIONAL ELECTROMAGNETIC-WAVES FOCUSED THROUGH AN INTERFACE, Pure and applied optics, 7(3), 1998, pp. 627-641
We compare theoretical and experimental results for focusing of two-di
mensional electromagnetic waves through a plane interface. In general,
good agreement is found when account is taken of possible aberrations
. However, when the relative refractive index between the two media be
comes large, discrepancies are observed due to reflections from the ba
ck surface of the second medium.
