A preliminary design of a knot undulator [PDF]

Journal of Synchrotron Radiation, 2012
The magnetic field configuration of the previously proposed knot undulator [Qiaoet al.(2009).Rev. Sci. Instrum.80, 085108] is realised in the design of a hybridized elliptically polarized undulator, which is presented. Although the details of the field distribution are not the same as those in the theoretical proposal, it is demonstrated that the ...

Preliminary Design of a Flexible Haptic Surface

, 2022
AbstractThis paper presents the preliminary development of a flexible haptic surface in order to produce texture rendering on a large conformable area. For this purpose, Haptic Pixels vibrating at ultrasonic frequencies are actuated by piezoelectric elements and implanted on a flexible matrix. The design leads to square glass plates of 10 $$\times $$
