Physical implementation of elements with fractal impedance: State of the art and prospects

Аннотация

In this review, we consider elements with a fractal impedance (henceforward, fractal elements, FEs). Advantages and drawbacks of various engineering and technological implementations of FEs are estimated. It is shown that promising FEs appropriate for production and solution of a wide range of scientific and engineering problems are structures on the basis of resistance-capacitance distributed parameter components (RC-DPCs) with the R–C–NR layer structure. It is established that RC-DPC FEs make it possible to implement fractal impedances with complex fractional-power frequency dependence. Examples of physical implementation of RC-DPC FEs are presented.
