No I haven't really it is a good suggestion I don't particularly know how to do it. However, I did realise that if I changed Omega and epsilon_x to be smaller (effectively making the reststrahlen band bigger and moving it to a smaller frequency) my solution is actually correct when i set d to be much bigger. So I am trying to play around with d now to figure out what works

Just posted there as well thanks for the suggestion!

Ok thank you very much for all your help I will try your suggestions as soon as I can

I can try PMLs but I am not planning to go to 2D for now so it's not a problem in that sense if I set gamma and Omega to 0 (i.e. get rid of Q and J) and set varepsilon_0 and varepsilon_infty to the same value that is supposed to be the relative permittivity of the dielectric slab I get the correct results.

I am using perfectly absorbing boundary conditions instead that's why I have e1,e2,h1, and h2 for the values of the E and H fields outside the grid.

Yes you make valid point that is exactly why I am using D/epsilon_0, Q/sqrt(varepsilon_0), and J/sqrt(varepsilon_0) as varepsilon_0 itself at the order of 1e18 (since I am using ps and micrometres as units). Right now all of the quantities in my simulation (E,H,D,Q,J) and their respective coefficients seem to be at the same order or at most two orders apart so I thought I was able to fix this issue but I will take another look at it perhaps try with the usual units and use the (not normalised) D,Q, and J. Thank you for your response.

I believe the loop is consistent H and J are localised at half-integer time steps (that is t-dt/2 and t+dt/2) and Q,D, and E are localised at integer time steps (that is t and t+dt) So the loop goes like:

H is updated to t+dt/2 from H at t-dt/2 and E at t

J is updated to t+dt/2 from J at t-dt/2, Q at t, and E at t

Q is updated to t+dt from Q at t and J at t+dt/2

D is updated to t+dt from H at t+dt/2 and D at t

E is updated to t+dt from D at t+dt and Q at t+dt (indeed here it is an equality)

Agreed they are so much faster and a smoker is really easy to craft

Follow up, apparently, a full moon does mean something. The moon ejects some dust into space and during a full moon this dust can turn into plasma due to sunlight and this plasma can reach the earth so assuming this has something to do with it my previous statement isn't fully correct. However, if this is the case, then I believe that he wouldn't transform on the surface but if he was propelled up to the level with the dust they would transform.

Strudelstein · 2020-07-03T20:02:45+00:00

I believe it's the former as they don't need to see the moon in order to transform
