Dear all, the product of conductivity and permittivity in "material dispersion"
http://ab-initio.mit.edu/wiki/index.php/Material_dispersion_in_Meep An imaginary part of permittivity is given by (D-conductivity)*(epsilon)/(omega). What's the product rule if D-conductivity and epsilon are tensor? Namely, if D-conductivity=[x 0 0; 0 y 0; 0 0 z], epsilon=[a u b; u b w; v w c] then which is true? permittivity=[a+i*a*x/w u+i*x*u/w v+i*x*v/w;.........] (followed by matrix product) or permittivity=[a+i*a*x/w u v ;.........] (followed by (permittivity_1_2) = i*(conductivity_1_2) *(epsilon_1_2)/w + (epsilon_1_2)) thanks _______________________________________________ meep-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
