Integration concept of an Electron Cyclotron System in DEMO

René Chavan, Minh Quang Tran, Hartmut Zohm, Konstantinos Avramidis

The pre-conceptual layout for an electron cyclotron system (ECS) in DEMO is described. The present DEMO ECS considers only equatorial ports for both plasma heating and neoclassical tearing mode (NTM) control. This differs from ITER, where four launchers in ...

Localization of Electromagnetic Interference Sources Using a Time-Reversal Cavity

Farhad Rachidi-Haeri, Marcos Rubinstein, Mohammad Azadifar, Hamidreza Karami, Amirhossein Mostajabi

In this article, we propose and implement a novel technique to locate electromagnetic interference (EMI) sources using the concept of time-reversal (TR) cavity. We show in an intuitive manner that reflections from the surfaces of a cavity can emulate an in ...

Antennas for CubeSat Communication

Miroslav Veljovic

CubeSats are a type of small satellites (< 500 kg) that weigh several kilograms and consist of multiple Units (U) measuring 100 × 100 × 113.5 mm3. CubeSats emerged as a low-cost alternative to conventional large satellites, and have since demonstrated capa ...

High-Frequency GaN-on-Si power integrated circuits based on Tri-Anode SBDs

Elison de Nazareth Matioli, Jun Ma, Georgios Kampitsis, Remco Franciscus Peter van Erp, Luca Nela, Halil Kerim Yildirim

In this work, we report on the switching performance of AlGaN/GaN lateral Tri-Anode SBDs. The Tri-Anode architecture leads to a more than 50% reduction in the device charge with respect to conventional planar structure, confirmed both by capacitive and rev ...

Temporal Modulation of Bianisotropic Metasurfaces for Unidirectional Wave Amplification

Xiaoqiang Wang, Mohammad Sajjad Mirmoosa, Xiao Wang

Nonreciprocity in time-modulated metasurfaces is normally achieved only when it is combined with with space modulation, using at least two time-varying elements located at different positions in space. In this talk, we present the idea of time-modulated bi ...
