Noise pollution is a challenging issue requiring the development of acoustic systems that can reduce noise. Besides environmental impacts noise pollution, it cause serious health problems. This work originally discusses reduction using new configuration side branches grafted in series with different terminations. The combination two serial resonators shows coupling effects. effect used to incre...

The paper presents a novel, unified technique to evaluate, through physics-based modeling, the frequency conversion and noise behavior of semiconductor devices operating in large-signal periodic regime. Starting from the harmonic balance (HB) solution of the spatially discretized physics-based model under (quasi) periodic forced operation, frequency conversion at the device ports in the presenc...

Studies about the constructive aspects of noise and fluctuations in different non-linear systems have shown that the addition of external noise to systems with an intrinsic noise may result in a less noisy response. Recently, the possibility to reduce the diffusion noise in semiconductor bulk materials by adding a random fluctuating contribution to the driving static electric field has been tes...
