Webarg(a) returns the phase. conj(a) returns the complex conjugate. realdot(a,b) returns the dot product of the two input arguments. The result is identical to real(a*conj(b)), but also will define the correct partial derivatives. In many cases, especially in electromagnetics, a complex-valued vector field (such as the electric field) is of interest. http://www.chemecomp.com/Comsol_intro_from_Ch.9.pdf

Plot magnitude and phase of complex derived values

http://www.chemecomp.com/Comsol_intro_from_Ch.9.pdf Webis not the only way to incorporate complex numbers (and hence absorption) into the equations. An alternate method is to use a complex conductivity instead of a complex relative permittivity. Typically either one or the other is done, but not both. Therefore we will assume for now that the conductivity from Ohm’s law, 𝐉𝜎𝐄 is a real ... medline knockdown bath bench with back
