A novel procedure to calculatte the induced current densit on large gently undulated surfaces has been presented. The method is based on the use of high-frequency derived basis functions, which also accounts for the undulation of the surface. By employing these basis functions in an integral equation procedure, electrically large problems can be handled in a computationally efficient and numerically rigorous manner, considering, at the same time, the random characteristics of the surface undulations.

Abstract
A novel procedure to calculatte the induced current densit on large gently undulated surfaces has been presented. The method is based on the use of high-frequency derived basis functions, which also accounts for the undulation of the surface. By employing these basis functions in an integral equation procedure, electrically large problems can be handled in a computationally efficient and numerically rigorous manner, considering, at the same time, the random characteristics of the surface undulations.File in questo prodotto:
