Transmission-line networks cloaking objects from electromagnetic fields
Pekka Alitalo, Olli Luukkonen, Liisi Jylhä +2
We consider a novel method of cloaking objects from the surrounding electromagnetic fields in the microwave region. The method is based on transmission-line networks that simulate…
A three-dimensional backward-wave network matched with free space
Pekka Alitalo, Olli Luukkonen, Sergei Tretyakov
A backward-wave slab based on a capacitively and inductively loaded three-dimensional transmission-line network is designed in such a way that impedance-matching with free space is…
Mesoscopic effective material parameters for thin layers modeled as single and double grids of interacting loaded wires
Pekka Ikonen, Elena Saenz, Ramon Gonzalo +2
As an example of thin composite layers we consider single and double grids of periodically arranged interacting wires loaded with a certain distributed reactive impedance. Currents…
Magnification of Subwavelength Field Distributions at Microwave Frequencies Using a Wire Medium Slab Operating in the Canalization Regime
Pekka Ikonen, Pavel Belov, Constantin Simovski +2
Magnification of subwavelength field distributions using a wire medium slab operating in the canalization regime is demonstrated using numerical simulations. The magnifying slab is…
On the Definition of Effective Permittivity and Permeability For Thin Composite Layers
Elena Saenz, Pekka Ikonen, Ramon Gonzalo +1
The problem of definition of effective material parameters (permittivity and permeability) for composite layers containing only one-two parallel arrays of complex-shaped inclusions…
Subwavelength resolution with three-dimensional isotropic transmission-line lenses
Pekka Alitalo, Sergei Tretyakov
Dispersion, impedance matching and resolution characteristics of an isotropic three-dimensional flat lens ("superlens") are studied. The lens is based on cubic meshes of interconne…
