lc filter simulink model

Hey guys,

 I'm sending you a picture of a equivalent model of the output LC filter in the laplace domain. Could you, please, tell me how I can implement this in simulink. Because the transfer function LC*s^2+1 cannot be implemented in simulink, it shows a warning that the degree of denominator must be equal or greater than the numerator.
