However, electro-mechanical parameters, e.g., low switching speed, high operating voltage, stiction probabilities, are limiting factors for the MEMS devices. In addition to scaling, these limiting factors are also addressed. 2 RF MEMS Scaling
WebTraditional anti-reflection coatings (ARCs) are based on destructive interference of light from two or more interfaces [1] [2]. The effects of using ARC layers are specially noticeable when the refractive indexes of the two media differ considerably [3]. A single layer of antireflection coating is not usually sufficient to achieve broadband ...
