Approximation of the first Steklov-Dirichlet eigenvalue on eccentric spherical shells in general dimensions
Jiho Hong, Woojoo Lee, Mikyoung Lim
We study the first Steklov-Dirichlet eigenvalue on eccentric spherical shells in with , imposing the Steklov condition on the outer boundary sphere, den…
Monostatic imaging of an extended target with MCMC sampling
Jiho Hong, Sangwoo Kang, Mikyoung Lim
We consider the imaging of a planar extended target from far-field data under a monostatic measurement configuration, in which the data is measured by a single moving transducer, a…
On the first Steklov-Dirichlet eigenvalue on eccentric annuli in general dimensions
Jiho Hong, Mikyoung Lim, Dong-Hwi Seo
We consider the Steklov-Dirichlet eigenvalue problem on eccentric annuli in Euclidean space of general dimensions. In recent work by the same authors of this paper [21], a limiting…
The Eigenvalue Problem for the Laplacian via Conformal Mapping and the Gohberg--Sigal Theory
Marius Beceanu, Jiho Hong, Hyun-Kyoung Kwon +1
We consider the Dirichlet and Neumann eigenvalues of the Laplacian for a planar, simply connected domain. The eigenvalues admit a characterization in terms of a layer potential of…
Shape monotonicity of the first Steklov-Dirichlet eigenvalue on eccentric annuli
Jiho Hong, Mikyoung Lim, Dong-Hwi Seo
In this paper, we investigate the monotonicity of the first Steklov--Dirichlet eigenvalue on eccentric annuli with respect to the distance, namely , between the centers of the i…
Characterization of stress concentration in two-dimensional boundary value problems: Neumann-type and Dirichlet-type
Jiho Hong, Mikyoung Lim
We consider a boundary value problem for the conductivity equation in a bounded domain containing an inclusion which is nearly touching to the domain's boundary. We assume that the…
Interdimensional optical isospectrality inspired by graph networks
Sunkyu Yu, Xianji Piao, Jiho Hong +1
A network picture has been applied to various physical and biological systems to understand their governing mechanisms intuitively. Utilizing discretization schemes, both electrica…
Metadisorder for designer light in random-walk systems
Sunkyu Yu, Xianji Piao, Jiho Hong +1
Disorder plays a critical role in signal transport, by controlling the correlation of systems. In wave physics, disordered potentials suppress wave transport due to their localized…
Progress toward high-Q perfect absorption: A Fano antilaser
Sunkyu Yu, Xianji Piao, Jiho Hong +1
Here we propose a route to the high-Q perfect absorption of light by introducing the concept of a Fano anti-laser. Based on the drastic spectral variation of the optical phase in a…
Bloch-like waves in random-walk potentials based on supersymmetry
Sunkyu Yu, Xianji Piao, Jiho Hong +1
Bloch's theorem was a major milestone that established the principle of bandgaps in crystals. Although it was once believed that bandgaps could form only under conditions of period…
