Dr. Sam Stein is the VP of engineering at Symmetricom Timing Test and Measurement Division. Symmetricom engineers have recently developed a digital sampling technique for measuring phase noise in ...

Quantitative phase imaging is a powerful, non-invasive and quantitative microscopy technique that allows multi-scale imaging of cellular systems, explain Mustafa Mir and Gabriel Popescu Imaging by ...

A while back, one of our coworkers was working on some of the challenges that are inherent in designing smartwatches, fitness wearables, and the like. One of the main challenges is how to get better ...

A new holographic storage technique uses light in three dimensions to dramatically increase how much data can be stored. It encodes information throughout a material using amplitude, phase, and ...

Fresnel diffraction describes the complex light propagation that occurs when a wavefront encounters an abrupt phase change, typically at the boundary of two different media or at an engineered phase ...

As commercial, military/aerospace, and other communications designs extend into the millimeter wave (mmWave) spectrum, engineers must adapt their testing procedures and require more from instruments ...

Researchers have demonstrated a new technique for precisely controlling phase boundaries in thin film materials by manipulating the thickness of those films – allowing them to engineer energy storage ...

Fig 1. Designers can parallel identical fixed-ratio isolated bus converters to create the high-power array in an intermediate bus architecture. Fig 2. This array of identical fixed-ratio isolated bus ...

CluMPS—Clusters Magnified by Phase Separation—is a fluorescent reporter strategy for detecting protein clusters. It promises to facilitate the visualization of protein clusters that are too small to ...

pH can have a huge effect on any SPE technique and can be utilized to enhance retention of compounds on an SPE product. For instance, the reversed phase technique can be used to adjust pH to ...
