“…In the experiments, the planar near-field measurement of the metasurface is implemented by discretizing and scanning a planar surface 200 mm away from the metasurface with the overall range of 760 mm × 760 mm. [40] The horn feeder and the open-ended waveguide probe are placed on the two sides of the metasurface and connected to the two ports of the PNA network analyzer Keysight N5222A. The metasurface is kept stationary while the waveguide probe scanning the signals throughout the sample plane.…”

Metasurfaces have been extensively studied for generating electromagnetic waves carrying orbital angular momentum (OAM). In particular, programmable metasurfaces enable real‐time switching between multiple OAM modes in a digital manner. However, the current programmable metasurfaces are mostly based on reflective mode, which suffer from low efficiency as well as serious feed blockage. In this paper, a transmissive programmable metasurface is presented for the highly efficient generation of multimode convergent OAM beams. The proposed transmissive metasurface is composed of electronically reconfigurable units with 1‐bit phase resolution (0/π), which are obtained by integrating two PIN diodes in the radiating layer for current direction modulation. Through the antisymmetry configuration of the two PIN diodes, nearly uniform transmission magnitudes but inversed phase states in a wide band can be obtained. The simulation results show that the proposed reconfigurable unit can achieve good 1‐bit phase tuning, with minimum insertion loss of 0.2 dB and 2 dB transmission bandwidth of more than 10%. Through the dynamic modulation of the quantized code distributions on the metasurface, programmable multimode OAM beams can thus be constructed. Both simulated and measured results verify the effectiveness of the proposed design.

“…Newly evolving digital communication systems require the reliable generation, transmission, and detection of digital signals. The efforts of the UME, INRIM, METAS, NPL, CMI, Abdullah Gül University (AGU), Delft University of Technology (TU Delft), Institut d'électronique et de télécommunications de Rennes (IETR) and Orbit/FR-Europe GmbH (Orbit) have result in providing metrological support through the characterization of mm-wave antenna arrays operating at the required frequencies [95][96][97] and the traceable calibration of instrumentation, which is used to detect and generate digital signals [98,99]. More specifically measurement methods for signals emitted from long term evolution (LTE) base stations have been made available by METAS and ETHZ [100] to reliably determine the power levels of the latest telecommunication standard, which is currently being adopted globally.…”

Metrology in electricity and magnetism: EURAMET activities today and tomorrow

et al. 2017

Metrology dedicated to electricity and magnetism has changed considerably in recent years. It encompasses almost all modern scientific, industrial, and societal challenges, e.g. the revision of the International System of Units, the profound transformation of industry, changes in energy use and generation, health, and environment, as well as nanotechnologies (including graphene and 2D materials) and quantum engineering. Over the same period, driven by the globalization of worldwide trade, the Mutual Recognition Arrangement (referred to as the CIPM MRA) was set up. As a result, the regional metrology organizations (RMOs) of national metrology institutes have grown in significance. EURAMET is the European RMO and has been very prominent in developing a strategic research agenda (SRA) and has established a comprehensive research programme. This paper reviews the highlights of EURAMET in electrical metrology within the European Metrology Research Programme and its main contributions to the CIPM MRA. In 2012 EURAMET undertook an extensive roadmapping exercise for proposed activities for the next decade which will also be discussed in this paper. This work has resulted in a new SRA of the second largest European funding programme: European Metrology Programme for Innovation and Research.
