Hello, everyone! I’m trying to finish a TDFEM program for electromagnetics. This is my reference paper:  
R. N. Rieben and D. A. White, “Verification of high-order mixed finite-element solution of transient magnetic diffusion problems,” in _IEEE Transactions on Magnetics_ , vol. 42, no. 1, pp. 25-39, Jan. 2006, doi: 10.1109/TMAG.2005.860127.  
The Whitney-2 forms basis function mentioned i.e. div-conforming basis functions in this paper is not given the higher order expressions. Could someone share the related information or detailed paper with me? And I am not major in mathematics. I am afraid I can’t understrand the complicated expressions.
