The 4 × 4 transformation matrix introduces newly defined vector products. In a Theorem the surface integral of one of the newly defined vector products is shown to be reduced to a line integral. %K Electromagnetic Field %K Parallel-Vertical Product %K Surface Integral %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=3970
