Then, in the early 70s, I attended a hi-fi show at the Olympia London and low and behold, there was Acoustic Research with its full lineup, including the mighty LST speaker plus its smaller AR-3a, AR-2ax, AR-6 and AR-7 models. The company was using Crown and Phase Linear amps ...

These RF front ends require many more analogue components to be integrated in a compact form factor, driving research in RF integration into traditional digital processes. Many high-performance technologies require integration using microelectromechanical systems (MEMS)-first or MEMS-last process schemes8...
Li Fan, Shu-yi Zhang, Xiao-juan Li, Hui Zhang & Jin Ding With the advance of the research on acoustic metamaterials, the limits of passive metamaterials have been observed, which prompts the studies concerning actively tunable metamaterials with adjustable characteristic frequency bands....

ODSAR can also be used to study the depth-averaged device strain for different resonant mode families. We first identify two high-Q modes corresponding to the Lamb flexural A0 and S0 extensional mode families of the device (Fig. 3a and Supplementary Fig. 2). One-dimensional scans along the...
