An Electric field has the following form in free space;
E=Re{Eo exp[j(ωt-κy)[itex]\hat{i}[/itex]
I am confused as to why a unit i vector is in the expression for an electric field oscillating in the Y direction? and also what does the Re mean ? i was reading somewhere about it being to do with rectangular coordinates.
