28 GHz Quadrature Frequency Generation Exploiting Injection-Locked Harmonic Extractors for 5G Communications

This paper proposes a mm-wave quadrature frequency generator using injection-locked harmonic extractors (HEs) incorporated with quadrature class-F oscillators. While maintaining high output levels at 28 GHz, the utilization of injection locking technique improves the effective quality ($Q$)-factor and helps to achieve a fundamental harmonic...

Three-bucket quadrature phase stepping in a shearing speckle interferometer

Phase stepping algorithms are mostly based on three or more interferograms that can either be acquired sequentially, involving some temporal phase stepping mechanism, or in parallel. When a phase step is applied between acquisitions, object phase changes may cause phase errors when calculating phase. A new system that allows the object to change...

CFD modeling of chemical reactors: Single-Phase Complex Reactions and Fine-Particle Production

Computational fluid dynamics (CFD) is a useful tool for modeling chemical reactors. However, because the design goals and expected outcomes are different than in "traditional'' CFD applications, chemical reactors require special attention to the treatment of chemical reactions, and heat and mass transfer. Here we provide an overview of the...
