Microwave Absorption for Detection of Dirac Fermions in SnTe Films
Advanced Materials Interfaces, EarlyView.Microwave absorption can detect Dirac fermions in samples exposed to the atmosphere. Results showed that although topological surface states are robust against environmental degradation, they are not detectable by electrical transport measurements. Hence, microwave absorption can detect Dirac fermions even in samples whose surfaces have deteriorated ...

Magnetically Actuated Drops‐on‐Stilts Microrobots for Transport and Delivery of Hydrophobic Cargo
Advanced Materials Interfaces, EarlyView.Iron oxide nanoparticles and oil droplets in external magnetic fields form “drops‐on‐stilts” microrobots that transport hydrophobic cargo. Tunable nanoparticle–droplet interactions generate stilt‐like structures. Field rotation enables walking, obstacle navigation, and collective motion.

On a Class of Degenerate Abstract Parabolic Problems and Applications to Some Eddy Current Models
, 2020 We present an abstract framework for parabolic type equations which possibly degenerate on certain spatial regions. The degeneracies are such that the equations under investigation may admit a type change ranging from parabolic to elliptic type problems.

Electromagnetic Phenomena as the Principles of Material Nondestructive Evalution
Advances in Electrical and Electronic Engineering, 2004 In the paper the principles and application of nondestructive evalution by both electromagnetic acoustic transducer (EMAT) and the eddy current (EC) methods are introducted. The ultrasonic testing (UT) and the electromagnetic nondestructive testing (NDT)

Physical Review Special Topics. Accelerators and Beams, 2011 A model is developed to study the eddy current induced in a thin conducting but nonmagnetic plate of finite size when exposed to a time varying magnetic field. The applied field may be uniform or vary in space. This model can accurately estimate the eddy
