Effects of Subharmonics in LO Generation on RF Transceivers
, 2018 Subharmonic residual in LO can degrade the performance of RF/mm-wave transceivers that employ frequency multipliers for LO generation. In this paper, we analyze the side effects that such subharmonics can cause. The effects are categorized to three parts:

Origin of broadband acoustic emission from a dancing cavitation bubble
Applied Physics ExpressAcoustic cavitation generates bubbles exhibiting violent expansion and contraction under intense ultrasound in liquids. The acoustic emissions (AE) spectrum from cavitation bubbles contains harmonics, subharmonics, ultraharmonics, and broadband noise ...

Emergence of subharmonics in a microwave driven dissipative Rydberg gas
Physical Review ResearchQuantum many-body systems near phase transitions respond collectively to externally applied perturbations. We explore this phenomenon in a laser-driven dissipative Rydberg gas that is tuned to a bistable regime.

Subharmonics increase the auditory impact of female koala rejection calls
, 2017 Although non-linear phenomena are common in human and non-human animal vocalisations, their functional relevance remains poorly understood. One theory posits that non-linear phenomena generate unpredictability in vocalisations, which increases the ...
