Realization of higher-order topology in bilayer asymmetric Su–Schrieffer–Heeger topological electric circuits

Applied Physics Letters
In this Letter, we report on the realization of higher-order topology in electric circuit systems by generalizing the two-dimensional asymmetric Su–Schrieffer–Heeger (SSH) model to a bilayer model, which consists of two monolayer models that are directly coupled.

TopoMEMS Circuit: Step-Variable-Resettable MEMS Capacitor for Topological Electrical Circuit

2021 21st International Conference on Solid-State Sensors, Actuators and Microsystems (Transducers), 2021
Recently, emulation of topological states based on electrical circuits draws much attention in view of future quantum computing. We have demonstrated a topological phase transition by switching a step-variable-resettable SOI-MEMS capacitor for the first time.

Topology optimization of conductors in electrical circuit

Structural and Multidisciplinary Optimization, 2019
This study proposes a topology optimization method for realizing a free-form design of conductors in electrical circuits. Conductors in a circuit must connect components, such as voltage sources, resistors, capacitors, and inductors, according to the given circuit diagram. The shape of conductors has a strong effect on the high-frequency performance of

Observation of Boundary‐Obstructed Topological Insulators in 2D Asymmetric Su–Schrieffer–Heeger Topological Electric Circuits

physica status solidi (RRL) – Rapid Research Letters, 2023
Topological insulators that support unique symmetry‐protected boundary states gain popularity in the field of electric circuit systems. Boundary‐obstructed topological (BOT) insulators, as a new class of topological insulators, do not utilize the closure of the bulk band during the topological phase transition, which displays as an obstruction of ...

Topology Optimization for Magnetic Circuits Dedicated to Electric Propulsion

IEEE Transactions on Magnetics, 2014
In this paper, we present a method to solve inverse problems of electromagnetic circuit design, which are formulated as a topology optimization problem. Indeed, by imposing the magnetic field inside a region, we search the best material distribution into variable domains.

Observation of corner states in second-order topological electric circuits

Physical Review B, 2020
Recently, the topological states in electric circuits have attracted a great deal of attention, and they have formed the basis of the field of so-called topoelectrical circuits. We realize a second-order topological electric circuit with capacitors and inductors, and we observe the corner states that exist in the bulk gap, the continuum of bulk modes ...

Topological simplification of electrical circuits by super-component analysis

2015 13th International Conference on Document Analysis and Recognition (ICDAR), 2015
An electrical or an electronic circuit often contains special combinations of circuit symbols in the form of sub-circuits. Identification and analysis of these sub-circuits can substantially simplify the underlying topology of a circuit. This paper explains our maiden attempt towards topological simplification of a circuit by identifying two important ...

Deriving electrical dependencies from circuit topologies using logic grammar

International Journal of Reasoning-based Intelligent Systems, 2009
In this paper, a new logic grammar for knowledge representation of electronic circuits has been developed. The grammar rules not only define the syntactic structure of electronic circuits, but also allow us to derive the meaning of a given circuit as relationships between its syntactic structure and basic circuit functions. This paper shows how voltage
