Band gap engineering metamaterials
웹2024년 3월 4일 · Nonlinear wave limiters transmit low-amplitude waves while blocking high-intensity ones for efficient target protection. However, the acoustical limiting effect in nonlinear materials remains hitherto unaddressed. In addition, tunable bandgap fosters advanced functions for devices, but it is still mostly regarded as a spatial and temporal invariant … 웹Acerca de. -Microwave Commissioning Engineer. 1999-2000 Siemens-Italtel. -Radio Network Engineer in Telefonica Moviles from 2000 to 2008. -Director and partner at Tafco Metawireless since January 2009. -In parallel, Assistant Lecturer at Public University of Navarra since 2003. -Internal instructor (Radio Network Technology) in Telefonica ...
