Observation of Klein bottle quadrupole topological insulators in electric circuits

Journal of Applied Physics
The Klein bottle insulator phase plays a pivotal role in understanding higher-order topological phases. The insulator phase is characterized by a unique feature: A nonsymmorphic glide symmetry that exists within momentum space, rather than real space.

Quadrupole topological phase and robust corner resonance in Kekulé hexagonal electric circuit

New Journal of Physics, 2020
Abstract Two-dimensional (2D) quadrupole topological insulators, featured by topologically protected 0D corner modes, have recently attracted tremendous interest in condensed matter and materials physics. Herein, we construct a specific electric circuit made of capacitors and inductors forming a 2D Kekulé hexagonal lattice for quadrupole

A Framework for Data-Driven Simulation of Electrical Circuits Based on Discrete-Continuous Optimization

IEEE Access
In this work, we present and investigate a new framework for the data-driven simulation of electrical circuits based on discrete-continuous optimization. For such an end, we provide a formal derivation of the data-driven discrete forward-dynamics problem

On-Site Wireless Power Generation

, 2018
Conventional wireless power transfer systems consist of a microwave power generator and a microwave power receiver separated by some distance. To realize efficient power transfer, the system is typically brought to resonance, and the coupled-antenna mode

Higher-order topological electric circuits and topological corner resonance on the breathing kagome and pyrochlore lattices

Physical Review B, 2018
Electric circuits are known to realize topological quadrupole insulators. We explore electric circuits made of capacitors and inductors forming the breathing Kagome and pyrochlore lattices. They are known to possess three phases (trivial insulator, higher-order topological insulator and metallic phases) in the tight-binding model. The topological phase
