Phase plus Antiphase radio waves

AI Thread Summary
When two waves are merged with one inverted, destructive interference occurs in certain areas, leading to a reduction in amplitude. However, energy is not lost; it redistributes to regions where constructive interference takes place. This means that while some areas experience cancellation, others will see an increase in energy. The overall effect is a complex interference pattern rather than total energy loss. Understanding this phenomenon is crucial for applications in radio wave transmission and signal processing.

If you produced a focused beam from, say, a cassegrain transmitter which consisted of two waves merged but one inverted what would be the result. I presume there would be destructive interference.
My question is, where does the energy go?

The energy goes to the regions where the interference is constructive. In other words, you can't get a purely destructive interference everywhere.

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...

Thread 'Effective absorption coefficient of gold nanoparticles'

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...

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...
