Seamless analysis from the DC to microwave frequencies is difficult task but essential to modern sub-micron integrated devices from the viewpoint of electromagnetic compatibility, in particular ELF and SAR problems to the human body. In this paper, we propose a new quasi-analytical approach taking the displacement current into account, for the full frequency analysis. Target conductive region can be subdivided into small cylindrical conductors having a simple geometrical shape. Because of the simple geometrical shape, it is possible to calculate an each of the resistances, inductances and capacitances of the subdivided conductors. This leads an equivalent circuit of the devices. Solving this equivalent circuit makes it possible to compute the electromagnetic field distributions exhibiting resonance phenomena. This paper applies our quasi-analytical approach to a simple finite length solenoid inductor. As a result, full wave solution reflecting on the practical frequency characteristics of the solenoid inductor could be obtained.
