High frequency electronic ballast provides line frequency lamp current [PDF]
, 2001 Most electronic ballasts for fluorescent lamps provide a sinusoidal lamp current at the switching frequency. The high-frequency current flowing through the lamp can generate significant radiated noise, which is unacceptable in noise-sensitive ...

Seeding-Layer-Free Deposition of High-k Dielectric on CVD Graphene for Enhanced Gate Control Ability
Crystals, 2022 The gate insulator is one of the most crucial factors determining the performance of a graphene field effect transistor (GFET). Good electrostatic control of the conduction channel by gate voltage requires thin gate oxides.

Synthesis of a high frequency reactance [PDF]
, 1939 Foster’s reactance theorem (1) provides the necessary information for the synthesis of the most general dissipationless reactance provided the frequency range is such that lumped reactances, namely inductance coils and condensers, are available.

Comparison of non-convex cost functionals for the consideration of phase differences in phaseless near-field far-field transformations of measured antenna fields [PDF]
Advances in Radio Science, 2017 This work introduces two methods which extend the non-convex minimization problem arising in phaseless (NF) far-field (FF) transformations. With the new extensions, knowledge about phase differences between measurement points can be incorporated into ...
