Deterministic-Statistical Approach for an Inverse Acoustic Source Problem using Multiple Frequency Limited Aperture Data
Yanfang Liu, Zhizhang Wu, Jiguang Sun +1
We propose a deterministic-statistical method for an inverse source problem using multiple frequency limited aperture far field data. The direct sampling method is used to obtain a…
FE-Holomorphic Operator Function Method for Nonlinear Plate Vibrations with Elastically Added Masses
Xiangying Pang, Jiguang Sun, Zhimin Zhang
Vibrations of structures subjected to concentrated point loads have many applications in mechanical engineering. Experiments are expensive and numerical methods are often used for…
Local estimators and Bayesian inverse problems with non-unique solutions
Jiguang Sun
The Bayesian approach is effective for inverse problems. The posterior density distribution provides useful information of the unknowns. However, for problems with non-unique solut…
A deterministic-statistical approach to reconstruct moving sources using sparse partial data
Yanfang Liu, Yukun Guo, Jiguang Sun
We consider the reconstruction of moving sources using partial measured data. A two-step deterministic-statistical approach is proposed. In the first step, an approximate direct sa…
An extended sampling-ensemble Kalman filter approach for partial data inverse elastic problems
Zhaoxing Li, Jiguang Sun, Liwei Xu
Inverse problems are more challenging when only partial data are available in general. In this paper, we propose a two-step approach combining the extended sampling method and the…
A Novel Computational Method for Band Structures of Dispersive Photonic Crystals
Wenqiang Xao, Jiguang Sun
We propose a new method to compute band structures of dispersive photonic crystals. It can treat arbitrarily frequency-dependent, lossy or lossless materials. The band structure pr…
