Abstract

We have simulated the distribution of electromagnetic (EM) waves through a system composed of miter bends by finite-difference time-domain (FDTD) simulation. To study the effect of mode conversion by miter bends, three shapes of miter bends have been simulated. For the miter bend that has processed grooves inside, the profile of the output EM waves is changed slightly from that of the input wave (HE 11 mode). As a result, this case exhibits the best shape of the miter bend in our simulation. In the miter bend without processed grooves inside, the output EM waves change more than in the case of the miter bend with grooves, because mode conversion occurs at the surface in miter bends without grooves. In the simple bend, which changes the direction of EM waves gradually, the profile of the output EM waves is deformed and the input profile is not conserved. Comparing the above three cases, we found that the grooves lead to more efficient to conservation of the profile of EM waves.
