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…
