Simplified single-phase clock scheme for MOBILE networks
(Institute of Electrical and Electronics Engineers, 2011)
MOBILE networks can be operated in a gate-level pipelined fashion allowing high through-output. If MOBILE gates are directly chained, a four-phase clock scheme is required for this. A single-phase scheme is possible adding ...

Dual capacitive-inductive nature of periodic graphene patches: Transmission characteristics at low-terahertz frequencies
(American Physical Society, 2013)
We report on the dual nature (capacitive and inductive) of the surface impedance of periodic graphene patches at low-terahertz frequencies. The transmission spectra of a graphene-dielectric stack shows that patterned ...

Concentration-polarization electroosmosis for particle fractionation
(Royal Society of Chemistry, 2024-05-03)
Concentration-polarization electroosmosis (CPEO) refers to steady-state electroosmotic flows around charged dielectric micro-particles induced by low-frequency AC electric fields. Recently, these flows were shown to cause ...
