摘要
In this paper, we study the energy decay rate of the wave-wave transmission system with Kelvin-Voigt damping on a rectangular domain. The damping is imposed on one of wave equations. By the separation of variables method and the frequency domain method, we show that the optimal energy decay rate of the system is t-2/3$$ {t} circumflex {-2/3} $$, which is independent of wave speeds.
