Chattez avec Graph Search
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.
In wireless communications, radio frequency micro-electro-mechanical systems (RF MEMS) technology is attracting tremendous interest across the world as the needs of frequencies gets higher, data bandwidth gets larger and multiple broadband signals have to ...
The present thesis deals with the electromagnetic modeling, design and practical implementation of a planar antenna for the reception of satellite broadcasting services from user terminals on board automotive platforms. This antenna is intended to address ...
The electric field enhancement associated with detailed structure within novel optical antenna nanostructures is modeled using the surface integral equation technique in the context of surface-enhanced Raman scattering (SERS). The antennae comprise random ...
The effect of substrate permittivity on UWB antenna radiation is studied. Microstrip and CPW-fed UWB monopoles are designed using substrates with different dielectric constants. The radiation patterns are measured. The transfer function of a two identical ...

For the universities of the emergent countries, and those of Cameroon in particular, the fight to reach a durable development requires to know the needed scientific and technical information for their development, how to get it and to spread it out among p ...
In this paper, a software tool for the prediction of the corona discharge and the multipactor thresholds in passive components based on rectangular geometry for space applications is presented.The software tool has been compare to measurements showing a ve ...
One of the most promising bands for long-range radiocommunications is the Ka-band (25-40 GHz). This is due to the existence of a natural radio transmission window around 30 GHz. Both terrestrial and satellite transmission systems are planned on this freque ...
The manufacture and characterisation of an elastic dipole antenna that is reversibly deformable and stretchable is described. The metallisation technique of depositing sub-micron-thick gold (Au) film on pillar patterned elastomer polydimethylsiloxane has b ...
This paper analyzes several mitigation strategies and techniques that could enable delay sensitive applications to work properly over satellite IP networks. A study is conducted on different satellite classes (GEO, MEO and LEO) and the analysis of the curr ...
The presence of free charges and numerous discontinuities separating liquid, gas, and solid phases in partially saturated soils give rise to Maxwell-Wagner polarization that may significantly affect bulk dielectric permittivity measurements. Evidence sugge ...
