In em wave gamma (propagation constant ) is equal to real no.(x) plus complex no. (y) . then attenuation constant is real no. and in some book is complex no.

In EM wave gamma (propagation constant ) is equal to real no.(x) plus complex no. (y) . then attenuation constant is given by real no. and in some book it given by complex no. , I confused which is true ? Mathew and saiduku is given real is attenuation constant and in David j Griffith it is given that complex is atennuation constant.
