The iPhone 17 Air is a design flex: a 5.64 mm ultra-thin iPhone with a gorgeous 6.6-inch Super Retina XDR OLED and A19-class speed. But RF-conscious buyers should pause—its hotspot and simultaneous SAR readings sit essentially at the FCC’s 1.6 W/kg ceiling. It’s a strong phone that demands safer-use discipline.

Jan 1, 2013
This study models nematic liquid crystals embedded in random polymer networks, where disorder disrupts long-range order and produces a glassy state. It uses simulations and an Imry-Ma-like analytic approach to visualize domains, predict domain size, and calculate the response to an applied electric field. The authors…
