For the purpose of designing FRF baselines, we propose a method to simplify a design formula of the amount of wave propagation. In this method, focusing on the interference of the wave, we approximate the amount of wave propagation by tactically ignoring the effect of near field waves. By using this formula, it is possible to design the target frequency ranges to minimize the wave propagation amount. In addition, this formula can be utilized as a design tool of the baseline of frequency response functions, which obeys wave interference on the waveguide. As a case study, it is shown that the wave propagation path can be changed by adding damping elements on a lattice structure. It is also shown that desired design of the baseline of frequency response functions is available by the change of wave propagation path.
