Theoretical Limits on the Efficiency of Reconfigurable and Nonreciprocal Graphene Antennas

Juan Ramon Mosig, Michele Tamagnone

Theoretical upper limits on the radiation efficiency of reconfigurable antennas based on graphene are presented in closed form and discussed. The theory provides useful information for the design of these structures independently of the type and geometry o ...

Near optimal graphene terahertz non-reciprocal isolator

Juan Ramon Mosig, Julien Perruisseau-Carrier, Mihai Adrian Ionescu, Clara-Fausta Moldovan, Michele Tamagnone

Isolators, or optical diodes, are devices enabling unidirectional light propagation by using non-reciprocal optical materials, namely materials able to break Lorentz reciprocity. The realization of isolators at terahertz frequencies is a very important ope ...

Efficient computation of Sommerfeld integral tails - methods and algorithms

Krzysztof Michalski, Juan Ramon Mosig

A review is presented of the most effective methods for the computation of Sommerfeld integral tails. Such integrals, which are often oscillatory, singular and divergent, commonly arise in layered media Green functions. The mathematical foundations of vari ...

Acoustic carpet cloak based on an ultrathin metasurface

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

An acoustic metasurface carpet cloak based on membrane-capped cavities is proposed and investigated numerically. This design has been chosen for allowing ultrathin geometries, although adapted to airborne sound frequencies in the range of 1 kHz (λ≈30 cm), ...

Field-enhanced design of steep-slope VO2 switches for low actuation voltage

Juan Ramon Mosig, Mihai Adrian Ionescu, Clara-Fausta Moldovan, Wolfgang Amadeus Vitale, Emanuele Andrea Casu, Michele Tamagnone, Luca Petit

The abrupt metal-insulator transition in vanadium dioxide (VO2) offers novel performance and functionality for beyond CMOS switches, enabling simultaneous high ON current and ultra-steep subthreshold slope with low temperature dependence. We developed a fi ...

Graphene quantum capacitors for high-Q tunable LC-tanks for RF ICs

Juan Ramon Mosig, Mihai Adrian Ionescu, Clara-Fausta Moldovan, Wolfgang Amadeus Vitale, Michele Tamagnone

We propose and characterize graphene quantum capacitors, tunable with voltage by the control of their charge density, for tunable LC tanks as essential building blocks for Radio-Frequency (RF) functions in densely integrated circuits. We fabricate and inve ...

Simplified Modal Expansion to Analyze Frequency-Selective Surfaces: An Equivalent Circuit Approach

Juan Ramon Mosig, Maria Garcia Vigueras

This communication extends a previously reported analytical circuit that models the plane wave scattering by 2-D arrays of planar patches/apertures embedded in a layered media. In this extension, it is assumed that the current/electric field spatial profil ...

Compact Microstrip Feedings with an Elevated Ground Plane for Thick Folded SIW

Juan Ramon Mosig, Lei Wang, Qi Wu

Folded substrate integrated waveguide (FSIW) has been proposed for further size reduction, while keeping the advantages of traditional SIW. FSIW-based horn antennas are very promising in millimeter wave applications. To improve the bandwidth and efficiency ...

Gate-controlled mid-infrared light bending with aperiodic graphene nanoribbons array

Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone

Graphene plasmonic nanostructures enable subwavelength confinement of electromagnetic energy from the mid-infrared down to the terahertz frequencies. By exploiting the spectrally varying light scattering phase at the vicinity of the resonant frequency of t ...

Low-loss Millimeter-wave Phase Shifters Based on Mechanical Reconfiguration

Juan Ramon Mosig, Julien Perruisseau-Carrier, Samuel Rosset, Herbert Shea, Pietro Romano, Oluwaseun Adelowo Araromi

We propose different concepts of mechanically reconfigurable true-time-delay phaseshifters using micro-actuators at millimeter-waves (MMW). The mechanical reconfiguration allows to achieve phase shift reconfiguration with very low losses. One of the propos ...

The Sommerfeld Halfspace Problem Redux: Alternative Field Representations, Role of Zenneck and Surface Plasmon Waves

Krzysztof Michalski, Juan Ramon Mosig

The problem of a vertical Hertzian dipole radiating in the presence of a lossy conducting halfspace, first formally solved by Sommerfeld in 1909, is revisited. Using rigorous operator theory concepts and the characteristic Green function procedure, alterna ...

Wideband, low profile and circularly polarized K/Ka band antenna

Juan Ramon Mosig, Joana Rita Alves dos Santos Silva, Przemyslaw Andrzej Gorski

This paper presents a wideband circularly polarized planar antenna element for both K and Ka bands. The proposed solution is composed by several thin layers of dielectric substrate that allocate two circular stacked patches, a crossed-slot and two fork-sha ...
