Fdtd Phase Reflection

AI Thread Summary

The discussion centers on simulating phase change due to reflection on gold using Ansys FDTD, specifically focusing on discrepancies between observed phase change tendencies and those reported in a reference paper. The setup includes a Frequency Domain Field and a Power monitor, with the light source positioned 1um above the sample. The user seeks insights to improve the simulation accuracy. Key concerns include the configuration of the E-field angle in x-polarization and the placement of monitoring equipment. Guidance from experienced users is requested to resolve these issues.

TL;DR Summary: I set up the FDTD simulation to simulating the phase change due to reflection of difference materials. But the result is not similar with the reference paper

Hello,

I am currently simulating phase change due to reflection on gold (Au) using Ansys FDTD. My setup includes using a Frequency Domain Field and a Power monitor to observe the angle of the E-field in x-polarization. However, the phase change tendencies I'm observing do not match those in my reference paper.
My configuration: The yellow X is Frequency Domain Field and a Power monitor. The light source is 1um above the sample and the monitor is 1um above the light source

My simulation and reference paper.

Could anyone provide insights or guidance on how to improve my simulation?

Thank you.

Thread 'The focal length of the eye and image inversion'

After my surgery this year, gas remained in my eye for a while. The light air bubbles appeared to sink to the bottom, and I realized that the brain was processing the information to invert the up/down/left/right image transferred to the retina. I have a question about optics and ophthalmology. Does the inversion of the image transferred to the retina depend on the position of the intraocular focal point of the lens of the eye? For example, in people with farsightedness, the focal point is...
