✦ Synopsis

w x used in 3 , and compare the results with that of the first-order Bayliss᎐Turkel boundary condition, which is widely applied in w x cylindrical coordinates 1 , and has the same number of nodes Ž . in space and time as that of the TDMEI in Eq. 2 . Compared with the MoM results, accurate results are obtained both in the TM and TE cases as depicted in Figure 5, where the number of meshes between the truncated boundary and the object surface is only ten.

CONCLUSION

A conformable time-domain truncated boundary condition based on the MEI concept is discussed in this paper. After the MEI coefficients have been determined accurately, the TDMEI can be used to truncate the FDTD mesh close to the object surface and with the same shape of the object surface. This novel boundary condition provides an efficient way to improve the conformability of the FDTD method.
