They show considerable potential in many applications, including vibration insulation, wave-guiding, noise control, and energy harvesting technologies. While the foundation of metamaterials research ...

This Collection aims to advance the understanding and development of acoustic and elastic metamaterials, with a particular focus on wave manipulation, vibration and noise control, and novel ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

An arbitrary waveform generator (AWG) is a powerful and flexible signal source capable of generating any wave shape within the bandwidth and amplitude range of the generator. Populating an AWG with ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...
