Study of additive manufactured microwave cavities for pulsed optically pumped atomic clock applications

Additive manufacturing (AM) of passive microwave components is of high interest for the cost-effective and rapid prototyping or manufacture of devices with complex geometries. Here, we present an experimental study on the properties of recently demonstrate ...

14 GHz longitudinally detected electron spin resonance using microHall sensors

Radivoje Popovic, Schahrazede-Lila Mouaziz, Malika Bouterfas

In this work we developed a home-made LOngitudinally Detected Electron Spin Resonance (LODESR) spectrometer based on a microsize Hall sensor. A coplanar waveguide (CPW)-resonator is used to induce microwave-excitation on the sample at 14 GHz. We used InSb ...

Wideband H-plane dielectric horn antenna

Juan Ramon Mosig, Lei Wang, Maria Garcia Vigueras, Marcos Alvarez Folgueiras

By flaring a dielectric waveguide in the H-plane, an H-plane dielectric horn is formed, which could be directly excited by an SIW feed. However, matching and radiation performances are poor due to the thinness of the substrate. To improve these performance ...

Development of Leaky-Wave Antenna Applications with Acoustics Metamaterials: from the Acoustic Dispersive Prism to Sound Direction Finding with a Single Microphone

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

Recent studies have focused on developing metamaterials for acoustic applications, inspired by electromagnetics concepts. The acoustic leaky-wave antenna is amongst the most investigated. Despite the unfavourable properties of conventional matter and struc ...

Exciton-polariton flows in cross-dimensional junctions

Hugo Pierre Alexandre Flayac

We study the nonequilibrium exciton-polariton condensation in 1D to 0D and 1D to quasi-2D junctions by means of non-resonant spectroscopy. The shape of our potential landscape allows to probe the resonant transmission of a propagating condensate between a ...

Polymer-Based Metal Coated Additive Manufactured V- and W-band Antenna Feed Chain Components

Juan Ramon Mosig, Emile Jacques de Rijk, Tomislav Debogovic, Santiago Capdevila Cascante, Esteban Menargues Gomez

In this paper an additive manufactured (AM) W-band monolithic feed chain is presented. The feed chain, which consists of a corrugated horn antenna and a turnstile orthomode transducer (OMT), operates over the entire W-band (75-110 GHz) and fulfills typical ...

Circularly Polarized Compact LTSA Array in SIW Technology

Juan Ramon Mosig, Marc Esquius Morote, Lei Wang

Typical linearly tapered slot antenna (LTSA) usually features a wideband and a high gain. However, its geometry size is large, especially very long in the tapering direction, which limits its application in compact antenna and array systems. This communica ...

Electromagnetic characterization of nonevaporable getter properties between 220-330 and 500-750 GHz for the Compact Linear Collider damping rings

Carlo Zannini, Eirini Koukovini Platia, Giovanni Rumolo

Due to its effective pumping ability, nonevaporable getter (NEG) coating is considered for the vacuum chambers of the Compact Linear Collider (CLIC) electron damping rings (EDR). The aim is to suppress fast beam ion instabilities. The electromagnetic (EM) ...
