In this work, coupling effect of the arbitrary impedance cylinder with any arbitrary cross section located between the parallel lines is investigated by using the method of moment techniques. We consider the two dimensional case as, lines and cylinder are infinite along the z axis. The effects of the induced currents on the impedance cylinder were expressed due to the current of line by numerically. The coupling degree of cylinder properties was investigated. As an example, coupling effect of the constant impedance circular cylinder is given for different impedance cylinder parameters.
