Hello all, I have an issue which I believe all you smart electrical engineers can help me with: How do you shield electronics from emf? I have a tablet pc with an active digitizer. The digitizer becomes inaccurate towards the peripheries of the screen --the closer to the bezel you are-- around the wifi radios and various electronics stuffed around the screen. Apparently the wacom digitizer does this because it picks up EMF signals from the rest of the computer. I want to shield my screen from these waves. My questions: 1. What is the difference between EMF and EMI in this application? 2. Is the tape I've seen online what i need to remedy this issue? To me, the layman, it just seems like aluminum or copper foil. If I need this, is there a place to get this cheap? 3. Anything else I should consider? Could I possibly short my screen out? 4. Does this sound like it may actually help with my digitizer? Thank You.
