Working Principle of Split Ring Resonators

AI Thread Summary
The discussion focuses on the physical working principle of Split Ring Resonators (SRRs) and their role in achieving negative permeability at a macro level. Participants seek a deeper understanding of the physics behind SRRs, including their equivalence to atomic magnetic models and the formation of capacitance. The conversation highlights the importance of current flow and electric fields within SRRs, emphasizing the need for detailed technical explanations. Several resources, including academic papers and Wikipedia, are suggested for further reading. Overall, the discussion aims to clarify the underlying mechanisms that contribute to the unique electromagnetic properties of SRRs.

What is the physical working principle of SRR's ?
How do they result in the negative permeability at a macro level?
(either of explanation or decent links will do!)


Thanks :biggrin:

Read : http://en.wikipedia.org/wiki/Split-ring_resonator
 
i have gone through this. what i was looking for is the actual physics supporting the functioning of the srr. wiki merely states its structure and characteristics.

how is it equivalent to an atomic (magnetic) model and what actually causes the negative permeability within the given freq range?

where exactly does the capacitance form and what role does it play?

how exactly, is the current flow/elec fields within etc.?

That would be a lot technical.

May be this is what you are looking for:

Does this help ?
 
What is the function of the splits on each ring in SRR's ?

The precise idea of that is given in the Wikipedia article in the introduction part. Read it.

For more details, refer to the links I mentioned in my previous post.
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
