Yarman Geometric Norm or Impedence Normalization

Click For Summary

Discussion Overview

The discussion revolves around the normalization of impedance values for antenna network optimization software, specifically focusing on the concept of Yarman geometric norm and its application in this context.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant seeks clarification on what it means to normalize impedance and how to perform this normalization for software that requires values to be set to 1 ohm.
  • Another participant suggests that normalization might involve dividing all impedances by the characteristic impedance of the system, such as 50 Ohms or 75 Ohms, while acknowledging that it could be more complex.
  • There is mention of difficulty in finding information about the Yarman geometric norm through online searches, indicating a lack of readily available resources.
  • A suggestion is made to search for "yarman antenna" as a potential avenue for more information.
  • A later reply indicates that the software uses a real frequency technique, which may relate to the normalization process discussed.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the specifics of the Yarman geometric norm or the normalization process, and multiple viewpoints and uncertainties remain regarding these concepts.

Contextual Notes

The discussion highlights the potential complexity of impedance normalization and the lack of clear references or definitions for the Yarman geometric norm, which may affect participants' understanding.

I'm working with some old software to optimize antenna networks, and I've come across some stuff that I don't understand. For the software to run, all impedence values entered must be normalized to 1 ohm. What does it mean to normalize an impedence and how do I do it? Also, the manual for the software keeps referring to a Yarman geometric norm when it talks about normalizing these impedences. What is a Yarman geometric norm?

I apologize if I sound daft. Any help would be much appreciated!

Hmm. Google is not very helpful with Yarman geometric norm, which is strange.

I'd guess that normalization would just be dividing all impedances by the characteristic impedance of the system you are working with (50 Ohms or 75 Ohms, etc.). But I suppose it could be more complicated than that.

The manual doesn't list any references? Does the company still exist and have a website? If not, do you see any author names that you could try to figure out how to contact to ask your questions?
 
Thanks Aleph! :smile:
 
Oh, okay! That actually makes more sense considering that the software uses the real frequency technique.
