Abstract
Gratings of infinite wires make, perhaps, the simplest class of metasurfaces, which, however, are utilized
for a variety of different objectives in wave manipulation. Importantly, due to their analytical solvability, they
can be fully optimized in a fast and direct way. In this study, a lattice of periodically corrugated cylindrical
particles under oblique plane-wave excitation is considered and treated rigorously. Several cases of particle radii,
distances between two consecutive cylinders, and angles of illumination are examined; as a result, very high
selectivity of the metasurface response in terms of line-of-sight transmission and absorption is reported. That
abrupt change in the device output becomes even more dramatic in the parametric vicinity of the emergence of
new refractive orders, which makes the proposed metasurface exceptionally fitting for switching, filtering, and
sensing applications
