Rtf huray model
Web[15] or [16]. Recently, Huray et al. proposed a physics-based “snowball” model for surface roughness [17] [18]. Their model is based upon analytic solutions for the fields surrounding a hemispherical ball attached to a metal surface. The Huray model has … WebIt is called Huray-Bracken model in Simbeor software [4] (it is multi-level). Expression (5) can be also rewritten in the causality-preserved form (7) that, apparently, is used in HFSS …
