DigestThe `rooftops' (RT) basis functions (BFs) are well suited for the modeling of geometries that conform to Cartesian coordinates, whereas the Rao, Wilton, and Glisson subdomains (RWG) BFs are capable of modeling flat-faceted approximations of arbitrary geometries. Both basis functions can also be used in modeling unknown functions transformed from the real space to the parametric space of a curved surface. The RT and RWG basis functions have many common features: they are defined on tow neighboring subdomains and the unknown is associated with the common edge between these two subdomains; thus they are edge functions. The two BFs also differ in the way they define the direction of the current.EnglishBoundary conditionsElectric fieldsFunctionsMathematical modelsBoundary condition error (BCE)Rao Wilton Glisson subdomainsPiecewise linear techniquesQuantitative comparison of rooftop and RWG basis functionsConference Paper10.1109/APS.1997.631581
