Effective medium theory for embedded obstacles in electromagnetic scattering with applications
Huaian Diao, Hongyu Liu, Qingle Meng +1
This paper focuses on the time-harmonic electromagnetic (EM) scattering problem in a general medium which may possess a nontrivial topological structure. We model this by an inhomo…

Stable determination of an impedance obstacle by a single far-field measurement
Huaian Diao, Hongyu Liu, Longyue Tao
We establish sharp stability estimates of logarithmic type in determining an impedance obstacle in . The obstacle is of general polygonal shape and the impedance para…

Determining anomalies in a semilinear elliptic equation by a minimal number of measurements
Huaian Diao, Xiaoxu Fei, Hongyu Liu +1
We are concerned with the inverse boundary problem of determining anomalies associated with a semilinear elliptic equation of the form , where $a(\mathbf x,…
