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…
Simple and accurate analytical model of planar grids and high-impedance surfaces comprising metal strips or patches
Olli Luukkonen, Constantin Simovski, Gérard Granet +4
This paper introduces simple analytical formulas for the grid impedance of electrically dense arrays of square patches and for the surface impedance of high-impedance surfaces base…
Modeling and Analysis of Composite Antenna Superstrates Consisting on Grids of Loaded Wires
Pekka Ikonen, Elena Saenz, Ramon Gonzalo +1
We study the characteristics and radiation mechanism of antenna superstrates based on closely located periodical grids of loaded wires. An explicit analytical method based on the l…
