Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

The gate-controllable complex conductivity of graphene offers unprecedented opportunities for reconfigurable plasmonics at terahertz and mid-infrared frequencies. However, the requirement of a gating electrode close to graphene and the single 'control knob ...

Recently the orbital angular momentum (OAM) multiplexing scheme has been proposed to increase supposedly without limit the channel capacity between a transmitter and a receiver nodes communicating in line of sight. A controversy arose about the far-field e ...

In recent years, there is a considerable and growing interest in developing fast integral equation methods for solving Maxwell’s equations. Volume integral equations are a versatile technique to model inhomogeneous scattering objects. Numerical tests show ...

A novel dual-band polarization-independent transmitarray is introduced in this paper for communication systems in Ka-band. Thanks to its unit-cell topology, the transmitarray antenna demonstrates almost complete independent performance at two design freque ...

This paper reports a novel methodology to design broadband orthomode transducers with two arbitrarily spaced ports carrying orthogonal linear polarizations. The component is based on a combination of two Boifot junctions through a series of power dividers ...

This paper presents a new methodology to measure the electromagnetic (EM) field using RFID tags, overcoming the limitations in dynamic range arisen by the conventional excitation of RFID tags. The methodology consists in the use of two different signals wh ...

In this paper, two THz reflectarray surfaces have been designed and fabricated in order to deflect a plane wave with any polarization and with a specific incident angle to three different specific directions each at distinct three frequencies of 0.7, 1.0 a ...
