Effects of Spatial Dispersion on Reflection from Mushroom-type Artificial Impedance Surfaces
Olli Luukkonen, Mário G. Silveirinha, Alexander B. Yakovlev +3
Several recent works have emphasized the role of spatial dispersion in wire media, and demonstrated that arrays of parallel metallic wires may behave very differently from a uniaxi…
A Thin Electromagnetic Absorber for Wide Incidence Angles and Both Polarizations
Olli Luukkonen, Filippo Costa, Agostino Monorchio +1
In this paper a planar electromagnetic absorber is introduced whose performance is maintained over a wide change of the incidence angle for both TE and TM polarization. The absorbe…
An Efficient and Simple Analytical Model for Analysis of Propagation Properties in Impedance Waveguides
Olli Luukkonen, Constantin R. Simovski, Antti V. Räisänen +1
In this paper propagation properties of a parallel-plate waveguide with tunable artificial impedance surfaces as sidewalls are studied both analytically and numerically. The impeda…
Toward creating isotropic microwave composites with negative refraction
C. R. Simovski, B. Sauviac
The properties of artificial isotropic microwave composites which would possess simultaneously negative permittivity and permeability are studied theoretically. Four kinds of compo…
Backward wave region and negative material parameters of a structure formed by lattices of wires and split-ring resonators
C. R. Simovski, P. A. Belov, S. He
A structure formed by combined lattices of infinitely long wires and split-ring resonators is studied. A dispersion equation is derived and then used to calculate the effective per…
