Mobile 'Lights': Impact on Signal Strength?

AI Thread Summary
Mobile light-emitting stickers may interfere with signal strength when used on devices, particularly when far from the antenna. Their size and placement could potentially create a barrier that weakens the signal, similar to a small Faraday cage effect. Concerns about connectivity arise due to the possibility of these stickers obstructing or absorbing signals. The impact on signal strength largely depends on the materials used in the stickers and their design. Overall, caution is advised when using such accessories if maintaining optimal signal connectivity is a priority.

mobile "lights"

I have seen some light making stickers sold that can be put on your mobile and they emit light when you talk. Am I right that they will lower my chances of getting connected when I am far from the antenna? I mean they must somehow make signal weaker, don;t they?

you would think , and depending on how big they are , they might act like a small Faraday cage .
 
Thread 'Simple math model for a Particle Image Velocimetry system'
Hello togehter, I am new to this forum and hope this post followed all the guidelines here (I tried to summarized my issue as clean as possible, two pictures are attached). I would appreciate every help: I am doing research on a Particle Image Velocimetry (PIV) system. For this I want to set a simple math model for the system. I hope you can help me out. Regarding this I have 2 main Questions. 1. I am trying to find a math model which is describing what is happening in a simple Particle...
I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
