Researchers have created a nanoscale structure that traps infrared light in a layer just 40 nanometers thick—over 1,000 times ...
Abstract: For synthesizing ultrawideband (UWB) beam-scanning aperiodic antenna arrays under mutual coupling (MC) effects, the novel constraint-reduced iterative convex optimization (CRICO) method with ...
Methods: This study used a mixed methods approach, combining qualitative and quantitative analyses. A focus group interview was conducted with 30 randomly selected older adults, and the interviews ...
Abstract: Large-scanned antenna arrays need to be periodically calibrated to correct for errors in excitation amplitude and phase, which degrade performance. The ability to adjust complex excitations ...
