Накратко на български

Радиочестотните схеми се използват за изучаване на топологични ефекти, като например създаването на стабилни електрически пътища по краищата на платката. Това помага за проектирането на електронни устройства, които работят надеждно дори при наличие на дефекти в компонентите.

Exploring topological phenomenon in RF circuits

This project shows successful attempts on the realization of novel topological effects in electrical circuits and provides many theoretical and experimental foundations for the future realization of many novel topological effects that are difficult to be implemented in in quantum electronics and photonics. The project combined ER and host supervisor’s expertise in theory of topological phases of matter and techniques of electrical circuit design, and equipped the ER to carry out cutting edge research in various topological circuits having unconventional topological effects. This project provides not only possibilities for designing novel RF circuits that could function properly under different types of circuit defects and tolerance, but also a new platform for exploring and experimentally demonstrating topological phenomena with ease and low cost. The proposed research work is truly multidisciplinary involving the investigation of topological materials (theoretical physics, condensed matter physics), designing and manufacturing RF circuit board (classical electro-magnetic wave, electric engineering), experimental characterization of nontrivial edge mode and Weyl degeneracies (electronic techniques), and developing accurate and efficient simulation tools for calculating circuit responses of both linear and nonlinear topological circuits (numerical methods and computer engineering). The overall objectives for the project “Topo-circuit” described in the proposal include the following four aspects: RO1: To develop two-dimensional topological circuits with nontrivial topological edge states, which are robust to various types of disorders and defects. RO2: To develop topological insulators on flexible substrates. RO3: To develop nonlinear topological circuits with topological properties depending on the input intensity. RO4: To use 3D topological circuits as a platform to study Weyl points and nodal lines at RF frequencies.

Цел на проекта

In this project, we aim to design and experimentally demonstrate topological phenomena in RF circuits. In particular, we will realize both two dimensional (2D) linear topological circuits showing nontrivial edge states immune from circuit defects and disorders, and nonlinear topological circuits whose topological properties can be controlled by the intensity of the input signal. To utilize the robustness nature of topological circuit, we will also fabricate flexible topological circuit on top of polyimide (PI) or polyethylene terephthalate (PET) films, where the topological features of circuit are preserved when the circuit is bent or stretched. 3D topological circuit will also be theoretically and numerically investigated to achieve exotic topological phases such as nodal lines and Weyl states at RF frequency. This project will provide not only possibilities for designing novel RF circuits that could function properly under different types of circuit defects and tolerance, but also a new platform for exploring and experimentally demonstrating topological phenomena with ease and low cost.
