Hi guys, this is just my idea of how ERR may work in spirit of trying to help,
Appologies to Dr Schwartz for errors as I don't really know the whole story.
I believe the ERR device is a magnifier just like a curved magnifying glass lens or more closely like a Fresnel lens. Instead of light being bent inward toward the focal point it works to bend EM waves inward toward it's focal point.
Not only this, it does a clever frequency shift by beating (heterodyning) incoming ambient energy frequencies with an internal voltage tuned generator frequency. The frequency difference a constant frequency band(f in - f local) appears across both halves of the waveguide which houses the left and right coils.
The slots or guides are run in transverse electric mode (TE) with voltage vertical across the narrow dimension of the slot and magnetic field sideways. Just like an aperture antenna often used in microwave.
The coils & slots are arranged in pairs 180 degrees out of phase with each other, when one side goes positive the other goes negative.
The outer width measured across the two slots defines a full wavelength at the highest frequency of the guides passband without mode changing.
The thickness of the aluminum slab which the slot is cut from defines the lowest frequency of the guide pass band.
The aluminum outer panel has a negative dielectric response to incoming EM radiation. This means the voltage part of the incoming field gets shifted in relation to the magnetic part of the field distorting its normal electric to magnetic phase relationship.
To bend the incoming wave completely just like a thick piece of glass or the surface of some water. We have to bend both the electric and the magnetic part of the wave.
When the advancing distorted wavefront appears on the inside of the aluminum it meets the Bismuth surface. Now Bismuth is diamagnetic it exhibits both Hall effect and an extremely non linear permeabilty to magnetic fields.
The coils in the guide slots underneath the Bismuth strobe the Bismuth surface magnetically.
Because the Bismuth layer is very thin compared to the incoming frequencies wavelength and because it's diamagnetic it has a negative response to magnetic fields. This bends the magnetic part of the incoming waves field.
The response from the Bismuth is able to act as a catalyst mobilising the atoms in the aluminum plate causing it to bulge and compress across it's surface making it act like a fresnel type lens to incoming EM radiation.
Causing it to behave like a hyper efficient lens literally BEAMING energy to the guide slots below.
To get extra bending toward the focal point in the centre of the guide cavity, extra layers of aluminum & bismuth can be added. Just like stacking lenses in a telescope or multi coating our spectacles (with metalic oxides).
The strobing of the non linear Bismuth also has another consequence.
When 2 frequencies are combined in something linear like a resistor we just get the same two frequencies out again they superimpose but don't mix as can be seen on a scope.
When 2 frequencies are combined in something non linear like our human ear or a piece of Bismuth or a semiconductor. We get sum and difference frequencies produced as well as the original frequencies.
The guide slots are tuned to pick off the difference frequency or narrower range of difference frequencies. The broader the bandwidth the higher the power available to us (from Boltzmans).
From here I am less sure, it may be .....from Dr Schwarts drawings.
Each turn of each coil on the rods themselves look like short circuit to the advancing RF wavefront down the guide. Simply because of the high stray capacitance at the start and finish of each turn & perhaps by the special winding technique of each turn.
Anyhow suffice to say there's a negative electric permittivity from the ferrite in the rod itself and a negative magnetic permeability from the special coil design.
When you drop a stone in a pond the waves radiate outward with exponentially diminishing amplitude.
With man made "Metamaterials" assembled as the genuis of Dr Schwarz has done it is possible to achieve the opposite.
ie Collect EM waves and concentrate them, just like a magnifying glass a microwave dish or a Yagi antenna does.
How the output becomes DC with out a rectifier? Don't really know only seen one paper on this concerning diffraction grating effects & can't understand it yet.
