Abstract:

The size of the baffle placed in front of BS to block the tail of the field from ITM was calculated using a FFT-based simulation tool SIS. The design is based to reduce the asymmetry introduced by the finite size of the BS mirror and to minimize the loss of the signal sideband. The baffle size is an oval shape with axis size 21cm x 26cm.
