Metasurface Doppler Cloak for Broadband Radar Stealth

open access: yesAdvanced Physics Research, Volume 4, Issue 10, October 2025.
Suppressing the motion‐induced Doppler shift passes the target as part of the static clutter which is ignored by radars. Using a simple time‐modulation, frequency conversion is obtained from a metasurface‐based solution over a wide range. Referred to as a Doppler cloak, this work expands and validates such a varactor‐loaded prototype for broadband ...

LTE MIMO throughput measurement method for characterization of multi-antenna terminal performance [PDF]

open access: yes, 2011
This paper presents experiences and results from LTE MIMO throughput measurements of a USB dongle in a reverberation test system. The measurements are performed with the dongle itself and also when it is connected to external diversity antennas with high

Study of a reverberation chamber shape inspired from chaotic cavities [PDF]

open access: yes, 2012
International audienceUsing the knowledge gained from the wave chaos theory, we present a simple modification of the shape of a reverberation chamber (RC) consisting in inserting a metallic hemisphere on a cavity wall.
