Hi, I am a very beginner to FDTD simulations. I already gave a function to calculate the refractive index in a cell. Now I have to make some fluctuations at some point say (-49.9, -49.9,0). I have provided my code below, but it doesn't seem to be giving me the required change. Am I doing something wrong?
*def indexret(p): #####function to define ref.index if p==mp.Vector3(-49.9,-49.9,0): n=1.78-0.43*(np.exp(-((p.y)+50)/71))+0.5 #change at (-49.9,-49.9,0) else: n=1.78-0.43*(np.exp(-((p.y)+50)/71)) return mp.Medium(index=n)cell = mp.Vector3(140,100,0)resolution=10geometry = [mp.Block(center=mp.Vector3(), size=mp.Vector3(140,100,0), material=indexret)] * Please help. Thank you *. * -- Krishna Nivedita G, Int.BS-MS, School of Physics, IISER Thiruvananthapuram.
