Abstract. The problem of matching
of array of planar dielectric waveguides with free space in a wide range of
angles is solved. Infinite array of planar dielectric waveguides is considered.
Array is excited by free space plane waves that incident on an array surface
under the arbitrary angle of incidence. Numerical solution of boundary problem
obtained with help of periodical boundary conditions and finite elements method
is considered. Specific features of numerical model are discussed. Approximate
solution for array of planar dielectric waveguides is considered. Comparison of
results obtained with help of numerical and approximate solutions is presented.
A way to improve the array matching with free space is proposed.
