Linear Polarization Interference: Can It Happen?

AI Thread Summary
Linear polarization interference occurs when two linearly polarized waves, one aligned with the x-axis and the other with the y-axis, interact. In a vacuum, these waves do not interfere because their electric fields are orthogonal, meaning they do not combine to form a resultant wave. The absence of matter that could alter the polarization is crucial, as any medium could potentially change the alignment and allow for interference. The discussion emphasizes the importance of understanding wave properties and polarization in physics. Ultimately, the consensus is that without external factors, linear polarization does not lead to interference.

Two waves are linearly polarized. The electric field of one wave is aligned with the x-axis and the other is aligned with the y-axis. In the absence of matter that might change the polarization, can these waves interfere with each other?

Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
