I am trying to study the optical properties of a leaf, which I have tried to model as a single layered structure, of the material with a refractive index of 1.4. I intend to study the Reflectance, Transmittance and Absorption of this material for 400 to 2500nm. The source I have selected is a plane wave source which is injected in the z axis. In essence, the model will only take into consideration the z dimension of the material since it is meant to mimic simulating a tiny portion of the leaf. The z span of the material has been set to 357 microns, the thickness of the leaf which I intend to model. The x and y span for the mesh has been arbitrarily set to a value of 10 microns (Is this the right thing to do?)
My mentor has mentioned that I will be able to obtain the 3 optical properties which I intend to study (Reflectance, Transmittance and Absorption) using the Frequency domain field and power monitor. However, I have tried some sample simulations with the same monitor and I am only able to get the result for Transmittance. May I know how I should go about calculating the results for Reflectance and Absorption?
Moreover, I have attempted to model the structure, wherein the Max time remaining for the simulation is shown to be around 14 hours, yet the simulation is complete in a matter of seconds. The resulting text document gives the following:
“0% complete. Max time remaining: 117 hrs, 18 mins, 16 secs. Auto Shutoff: 1
100% complete. Max time remaining: 0 mins, 0 secs. Auto Shutoff: 0
Early termination of simulation, the autoshutoff criteria are satisfied.”
I am unsure what to make of this information, and when I attempt to visualise the resulting values for Transmittance with the monitor, I obtain the following message “Failed to calculate results!”. Could any kind soul help me to spot the error in my simulation file? I have attached it below:
Leaf model 1.fsp (2.7 MB)
Lastly, could anyone please advice on the feasibility of setting the minimum mesh step as 0.1 microns? Is this value too small or large for such a simulation?
If anybody could suggest how I should change the any of the simulation settings or answer any of the above questions, I would be eternally grateful. Thank You!
