As supply voltages get lower it becomes more of a challenge to accurately measure power supply ripple, or “noise,” on the power bus. Complicating factors include faster-switching power converters, ...
EMI from on-board DC-DC converters is a common problem with IoT products. These small circuits generally switch between 1 MHz and 3 MHz and use very fast sub-nanosecond edge speeds. The result is ...
A planar slab of negative-index material works as a superlens with sub-diffraction-limited resolution, as propagating waves are focused and, moreover, evanescent waves are reconstructed in the image ...
