Progagation on a waveguide

Hello
I want to simulate the propagation of light in a waveguide in the time domain. I used the RF module in the transient regime.
In the first simulation I created a material with refractive index n=3.1, a perfect electric conductor around the waveguide and a lumped port as a gaussean pulse source, and I got this result, which looks nice

But what I really want is the second simulation in which I put air on both sides of the waveguide. But the result is that light does not propagate, as you can see here
mega.co.nz/#!tx8CzZwS!lpQdw6z9lJuAXyUsPjemcWfAN759D52UuGWyisfY2_0
But it would be nice that the light would propagate. I don't understand why this happens. Do you know what is it happening?
Thanks!

It seems you are having trouble coupling the gaussian pulse inside the waveguide. There are to many possible causes. Can you upload the model so we can look at it?
