Isotropic Epsilon-Negative Particles
(IEEE, 2007-06)This paper presents two particles with negative permittivity in some frequency band. The response of a single dipole loaded by an inductance is strongly anisotropic. The response of a spider dipole does not depend on the ... -
Leakage Effects of Dominant and Higher Order Modes on Slotline
(IEEE, 1996-09)The properties of the slotline when the dominant bound or leaky wave propagates, together with the behaviour of new higher order modes are investigated. The frequency range in which the slotline transmits the bound wave ... -
Leaky Wave Radiation of a Printed Slotline Antenna
(IEEE, 2001)This paper presents a theoretical prediction of the field radiated from a uniplanar slotline antenna operating with the leaky wave. Discussion on a possible spectrum of space leaky waves is opened. Several antennas and ... -
Left-Handed Coplanar Waveguide
(IEEE, 2005-06)This paper proposes a new version of a left-handed coplanar waveguide. The line has a fully uniplanar structure without vias and lumped elements. The series capacitors are represented by interdigital capacitors and the ... -
Load Impedances of Complex Slotline Terminations
(IEEE, 1995-09)Single slotline has gained new interest due to application in uniplanar circuits, antennas or active radiators, all these including slotline short circuits or even more complex terminations. This paper gives a new approach ... -
Low Profile Slotted Flat Waveguide Leaky Wave Antenna
(IEEE, 2006-06)This paper presents the application of a flat waveguide with a longitudinal slot in the middle of its wider wall for the design of a leaky wave antenna. The antenna radiates into one relatively narrow main beam and its ... -

(IEEE, 2006-07)This letter presents a new version of an artificial dielectric substrate and a microstrip line built on top of this substrate. The substrate is fabricated as a two-dimensional array of metallic posts separated from the top ... -
Microwave reflectivity from gold sputtered nanolayer
(IEEE, 2007-11)This paper deals with reflectivity of a gold layer of nanometer-scale thickness sputtered on a dielectric foil at microwave frequencies. A model of nanometer-scale spheres characterizes the behavior of the layer. For short ... -
Modes on the Standard and Inverted Conductor-Backed Slotline
(IEEE, 2003-06)This paper recalls modes which can propagate on the conductor-backed slotline. The characteristic of the dominant mode on the CBSL is documented. The ICBSL is a modification of the CBSL placed in a dielectric with permittivity ... -

(IEEE, 2005-10)The design, analysis, fabrication and measurement of a new bulk metamaterial is reported in this paper. The structure of the new medium is made up of left-handed parallel strips. The series capacitors are realized by short ... -
New Space Leaky Wave Spectrum Components on the Slotline
(IEEE, 2000-10)Surface and space leakage of power deteriorates the operation of circuits. On the other hand space leaky waves enable the design of specific radiators. In this paper we therefore investigate the potential of the slotline ... -
