    Diode Model Tips
AI Thread Summary
Choosing the right diode model involves understanding the specific characteristics of the diode and the application requirements. It's essential to analyze the diode's behavior in different regions, especially when using a four-region model, to avoid contradictions in your calculations. Practical tips include starting with common diode types and consulting resources like Wikipedia for foundational knowledge. Providing examples of successful guesses can help clarify the selection process and identify potential issues. Mastering diode modeling is crucial for accurate circuit design and analysis.

I am just beginning to learn about diodes and I was wondering if there are any tips to making the correct guess for the diode model. For our class, we use a model that consists of four regions instead of the simple on/off model. basically to figure out what the diode is doing, we insert the model we guess and solve to see if there is a contradiction. This becomes annoying fast..

So what are your tips for picking the correct region for the diode?

Could you maybe provide an example of one of your guesses so we can see where the problem is. When you talk about models, I think of http://en.wikipedia.org/wiki/Diode_modelling" .

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
