Search for Lensing Signatures in the Gravitational-Wave Observations from the First Half of LIGO-Virgo's Third Observing Run

We search for signatures of gravitational lensing in the gravitational-wave signals from compact binary coalescences detected by Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) and Advanced Virgo during O3a, the first half of their third observing run. We study: (1) the expect...

I "new media", in un’azione didattica orientata alla promozione della competenza digitale

Il saggio ripercorre lo sviluppo del concetto di media education e propone una riflessione sulla new media literacy in relazione alle dimensioni previste per la competenza digitale considerata una delle competenze chiave per il life long learning e a come ciò impatta sui proc...

Surface Mountable L- And C-Band Pre-distorted Filters for Frequency Converters of High Throughput Satellite systems

In this paper the design and first experimental results of surface mountable bandpass filters in the L- and C- bands are presented. Used for frequency converters in High Throughput Satellite (HTS) systems, the L-band filter is centred at 960MHz with 500MHz bandwidth (FBW=52%) while...

Frequency Splitting and other Things that Filters and Wireless Power Transfer Systems have in Common

In this paper, the phenomenon of frequency splitting in resonating Wireless Power Transfer Systems is considered. In particular, the property of impedance inverters of converting an impedance into an admittance is here exploited to give a simple and intuitive explanation of that phenome...

Spurious suppression through the control of their couplings: Application to TM cavity filters

In this paper, a new approach for improving filter spurious free band is proposed. The main idea is to control the coupling coefficients of the spurious resonances in order to force them to cancel each other. The required coupling levels can be estimated by using an ...
