This article investigates the impact of ground vias placed in close proximity to high speed differential signal vias and the resulting differential mode to common mode conversion. The work shows the influence of the distance between ground (GND) vias and differential signal (Diff. SIG.); the effect of the asymmetrical configuration of the GND vias; the impact of the dielectric thickness and the number of transitions between the planes.

University of Arizona and University of Central Florida scientists are creating a new method that is capable of transmitting high-intensity laser beams through the atmosphere than what is currently possible. The goal of the project is to be able to guide electrical discharges, like lightning, away from buildings where lightning rods are limited.

Surveys show that price and performance are still the most important consumer criteria when selecting a mobile device.¹ However, increasing commoditization coupled with growing environmental concerns are placing sustainability front and center among considerations for manufacturers that hope to differentiate their products and demonstrate good corporate stewardship.
