Left-handed-media simulation and transmission of EM waves in subwavelength split-ring-resonator-loaded metallic waveguides
(American Physical Society, 2002-10-28)
At microwave frequencies, hollow metallic waveguides behave in certain aspects as a “one-dimensional plasma.” This feature will be advantageously used for simulating the propagation of electromagnetic (EM) waves in left-handed ...

Near-field enhanced imaging by a magnetized ferrite slab
(American Institute of Physics, 2005)
This letter demonstrates the near-field imaging enhancement at microwave frequencies of two-dimensional sources by a ferrite slab magnetized to saturation. It is shown that this effect is based on the nonreciprocal ...

Artificial magnetic metamaterial design by using spiral resonators
(American Physical Society, 2004)
A metallic planar particle, that will be called spiral resonator (SR), is introduced as a useful artificial atom for artificial magnetic media design and fabrication. A simple theoretical model which provides the most ...

Two-dimensional study of leaky modes in microstrip line with a semi-infinite cover layer
(Wiley-Blackwell, 2004)
This work presents a two-dimensional (2-D) study of the modal spectrum of a single microstrip and a pair of coupled microstrip lines with an upper dielectric half-space. This 2-D study is postulated as the necessary step ...
