WebJun 3, 2024 · The widely accepted models for calculating roughness correction factors are the Cannonball-Huray and Hammerstad models. The Cannonball-Huray model has more power and adaptability in terms of fitting to experimental data, but its form is more complex. WebThe Huray model has been a popular method to account for the additional signal loss due to copper surface roughness. Many researchers and scholars have been trying to build accurate models over the last decade based on Huray's work. In this article, I would like to share an intriguing story about the application of the Huray model: engineers from copper … can any animals understand english
