I'm involved in a project aiming to simulate, and later hopefully build, a negative lens for operation at 100GHz....a major stumbling block is extracting µ and ε from our HFSS simulations.
There are a lot of very vague articles that claim to have achieved 'doubly negative' parameters, which don't actually explain how they confirmed this.
Does anyone know of a (reasonably) simple way of extracting µ and ε? Or if all else fails and this is not possbile, could we prove the material is exhibiting a negative n value without actually going into detail about the parameters?
Any hints would be much appreciated!
