Non-diffracting chirped Bessel waves in optical antiguides
Ioannis Chremmos, Melpomeni Giamalaki
Chirped Bessel waves are introduced as stable (non-diffracting) solutions of the paraxial wave equation in optical antiguides with a power-law radial variation in their index of re…

Dynamic Effective Medium Theory for Two-Dimensional Non-Magnetic Metamaterial Lattices using Multipole Expansion
Ioannis Chremmos, Efthymios Kallos, Melpomeni Giamalaki +2
We present a formulation for deriving effective medium properties of infinitely periodic two-dimensional metamaterial lattice structures beyond the static and quasi-static limits.…
