image: Figure 1. Schematic of imaging under real-frequency and synthesised complex frequency excitation in a superlens. The same object, when imaged through a superlens under different real-frequency ...

Everyone interested in analog electronics should find some value in this post. Of course, an effort has been made here to make the content understandable to relative newbies. Forget about complex ...

Researchers report their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits.

The seismic signals from volcanoes are complex waves that result from multiple single waves that occur simultaneously. To help students understand how a complex wave is formed, tell them that in this ...

Alain Bourdillon is a professor of Electrical Engineering at the University de Rennes. He is involved in research on Over The Horizon radar and on radio propagation. Direct frequency synthesizers have ...

How to measure linearity of an ADC using sine-wave input. How do non-idealities of a sine wave affect ADC linearity while testing it. Testing an ADC’s linearity. To obtain the transfer function of an ...
