Unit Cell of Circuit Board (IMAGE)
Caption
On the right, a unit cell cutout of the circuit board, which was built to demonstrate the non-Hermitian skin effect, is shown. In (a), the underlying theoretical non-Hermitian model is sketched, which describes the couplings between adjacent nodes. (b) depicts a schematic diagram of the full circuit chain with 20 unit cells with either periodic (without boundary) or open boundary conditions. (c) Circuit schematic of the periodically repeated unit cell with two internal nodes.
