Resonant Interlayer Coupling in NbSe2‐Graphite Epitaxial Moiré Superlattices
Advanced Materials, EarlyView.Combining angle‐resolved photoemission spectroscopy and density functional theory derived calculations, this work reveals strong interlayer coupling and moiré replicas of the graphite π states in molecular‐beam epitaxy grown van der Waals heterostructures of monolayer‐NbSe2/graphite, with implications for its collective phases that form. Abstract Moiré

Analysis of Total Harmonic Distortion in Microspeaker Considering Coupling Effect
Transactions of the Korean Society for Noise and Vibration Engineering, 2008 With the advent of mobile phone, digital multimedia broadcasting(DMB) service is to be realized for multimedia data communication. For an acoustic part, a smaller and lighter microspeaker is also soon to be realized as an MP3 song player and a speakerphone. Sound quality in the microspeaker is becoming more important in mobile phones.

Minimizing total harmonic distortion in single phase inverters
, 2020 The first device that comes to mind in terms of quality and economy in energy systems in iverters. Inverters are the devices which convert the direct current to alternating current at the desired frequency and amplitude. It is desirable that do not contain u desired signals which are called harmonics. The first thing that comes to mind in the design of
