FDTD analysis of induced current of PEC wire which in contact with half space lossy ground by using surface impedance boundary condition

In recent years, electromagnetic waves are widely used. On the other hand, a fraction of electromagnetic waves are absorbed into the human body. In the case of far filed exposure, whole body resonance phenomena are observed at VHF frequency band when the component of E-field is parallel to the human body's height. In this phenomenon intensive induced current is observed in the human body. The induced current maybe depends on earth condition. In this paper, in order to estimate an effect of lossy flat earth for induced current, the induced current of object which is in contact with earth is analyzed by the FDTD method. The flat earth is modeld by using surface impedance boundary conditions to reduce calculation resources.
