Creating aperiodic photonic structures by synthesized Mathieu-Gauss beams
(Physical Review A, 2017)
We demonstrate a kind of aperiodic photonic structure realized using the interference of multiple Mathieu-Gauss beams. Depending on the beam configurations, their mutual distances, angles of rotation, or phase relations ...
Anomalous lateral beam shift and total absorption due to excitation of surface waves in materials with negative refraction
(EUROPEAN PHYSICAL JOURNAL D, 2006)
We studied electromagnetic beam reflection from layered structures that include materials with negative refraction. Excitation of leaky surface waves leads to the formation of anomalous lateral shifts in the reflected beams ...
Elliptical vortex necklaces in Mathieu lattices
(Physical Review A, 2018)
We demonstrate unusual kinds of discrete vortex beams, elliptical necklaces, realized by Mathieu photonic lattices. Varying the order of the Mathieu lattices and their ellipticity, we can control the shape and size of such ...
Alkali-activated systems – durability aspects and testing procedures
(Brno University of Technology & ŽPSV, a.s., Czech Republic, 2014)
This paper analyses existing testing procedures for the external sulfate attack on Portland cement systems and their applicability, as well as unavoidable modifications, for alkali-activated systems. The accelerated testing ...
