Abstract: The coupling effect of UWB to landmine is analyzed by
FDTD numerical method. Based on the shell structure and setting pose of
landmine, the difference equation is deduced on absorbing boundary condition
of CPML in Cylindrical coordinates. The dimension reduction of the TF/SF
connecting boundary condition is reduced to introduce the incident wave. In
order to improve calculating efficiency, the parallel FDTD method is
adopted. The calculating model is founded and numerical simulation of slot
coupling effect on landmine shielding shell is processed. The coupling
electromagnetic field of shells made with different shielding material and
with slots of different sizes is plotted. The slot coupling regulation of
UWB to shell is analyzed. It has some effect on landmine against
electromagnetic weapon damage and provides reference to modern landmine and
landmine sweeping system design.
