A Multi-Level Machine Learning Framework for Inverse Scattering Problems with Multi-Frequency Data
Yi Liu, Yanzhao Cao, Junshan Lin +1
In this work, we propose a multi-level machine learning framework for solving inverse scattering problems with multi-frequency data. The multi-level neural network is built along t…
Mathematical theory for the interface mode in a waveguide bifurcated from a Dirac point
Jiayu Qiu, Junshan Lin, Peng Xie +1
In this paper, we prove the existence of a bound state in a waveguide that consists of two semi-infinite periodic structures separated by an interface. The two periodic structures…
Dirac points for the honeycomb lattice with impenetrable obstacles
Wei Li, Junshan Lin, Hai Zhang
This work is concerned with the Dirac points for the honeycomb lattice with impenetrable obstacles arranged periodically in a homogeneous medium. We consider both the Dirichlet and…
Mathematical theory for electromagnetic scattering resonances and field enhancement in a subwavelength annular gap
Junshan Lin, Wangtao Lu, Hai Zhang
This work presents a mathematical theory for electromagnetic scattering resonances in a subwavelength annular hole embedded in a metallic slab, with the annulus width . The…
An adaptive boundary element method for the transmission problem with hyperbolic metamaterials
Junshan Lin
In this work we present an adaptive boundary element method for computing the electromagnetic response of wave interactions in hyperbolic metamaterials. One unique feature of hyper…
Mathematical theory for topological photonic materials in one dimension
Junshan Lin, Hai Zhang
This work presents a rigorous theory for topological photonic materials in one dimension. The main focus is on the existence and stability of interface modes that are induced by to…
