ABSTRACT
In this chapter, two-dimensional scattering problems are considered. Light will be restricted to propagation in the x y https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781351260206/4bca3869-f413-46d7-8ef0-9a5b65c1eb68/content/eq582.tif"/> -plane, and the electric and magnetic fields, and the dielectric constant of the structure of interest, are invariant along the z-axis. For the position vector we will use () r ≡ x ^ x + y ^ y , https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781351260206/4bca3869-f413-46d7-8ef0-9a5b65c1eb68/content/eq583.tif"/>
