A broadband and high-gain metamaterial microstrip antenna

Juan Ramon Mosig, Olivier Martin

A broad bandwidth and high gain rectangular patch antenna was specifically designed in this paper using planar-patterned metamaterial concepts. Based on an ordinary patch antenna, the antenna has isolated triangle gaps and crossed strip-line gaps etched on ...

Electromagnetic inspired acoustic leaky-wave antenna

Juan Ramon Mosig, Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

In this article we make an analogy between Electromagnetic and Acoustic transmission-line modelling. Then we use this to introduce acoustic transmission-line metamaterials and finally we introduce the acoustic leaky-wave antenna on the basis of previous st ...

Equivalent Admittance Approach for the Scattering of Patch/Slot-Based Frequency Selective Surfaces

Juan Ramon Mosig, Maria Garcia Vigueras

The equivalent admittance of a 2-D array of printed metallic patches/apertures is obtained here by extending a precedent equivalent circuit approach reported by some of the authors. The goal of the present extension is to cover more complex situations like ...

Oblique incidence design of meander-line polarizers for dielectric lens antennas

Juan Ramon Mosig, Jean-François Zürcher, Benjamin Fuchs, Benjamin Fuchs, Marco Letizia

A method to design planar multilayer meander-line polarizers is given. The proposed procedure is based on transmission line circuit theory and on full-wave unit cell analysis in frequency domain. The hybrid combination of those two techniques paves the way ...

Efficient algorithms for computing Sommerfeld integral tails

Juan Ramon Mosig, Athanasios Polymeridis, Ruzica Golubovic

Sommerfeld-integrals (SIs) are ubiquitous in the analysis of problems involving antennas and scatterers embedded in planar multilayered media. It is well known that the oscillating and slowly decaying nature of their integrands makes the numerical evaluati ...

A printed transition for matching improvement of SIW horn antennas

Juan Ramon Mosig, Jean-François Zürcher, Benjamin Fuchs, Benjamin Fuchs, Marc Esquius Morote

The substrate integrated waveguide (SIW) technology allows to construct several types of commonly used antennas in a planar way. However, frequency limitations associated to commercial substrates appear in the implementation of certain types of antennas, e ...

Enhanced backscattering by multiple nanocylinders illuminated by TE plane wave

Juan Ramon Mosig, Olivier Martin

In this paper, we study the multiple scattering by electrically small (the radius of the cylinder is much smaller than the wavelength) plasmonic nanocylinders near surface plasmon resonance. The cylinders are assumed to be identical in dimension and compos ...

Enhanced periodic structure analysis based on a multiconductor transmission line model and application to metamaterials

Juan Ramon Mosig, Julien Perruisseau-Carrier, Frédéric Bongard

We propose to model periodic structures by equivalent multiconductor transmission lines (MTLs). The developed technique is based on a multimodal representation of the periodic structure unit cell, such as required for periodically loaded MTLs and periodica ...
