In the near field, radiative heat transfer can exceed the prediction from Planck's law by several orders of magnitude, when the interacting materials support surface polaritons in the infrared range. However, if the emitter and absorber are made from two different materials, which support surface polariton resonances at different frequencies, the mismatch between surface polariton resonance fre...

in this paper vibration of ferromagnetic rectangular plates which are subjected to an inclined magnetic field is investigated based on classical plate theory and maxwell equations. levy type solution and finite element method using comsol software are used to obtain the frequency of the plate subjected to different boundary conditions, good agreements is obtained when computed results are compa...

With nanosecond radiative lifetimes, quenching dominates over enhancement for conventional fluorescence emitters near metal interfaces. We explore the fundamentally distinct behavior of photoluminescence (PL) with few-femtosecond radiative lifetimes of a coupled plasmonic emitter. Controlling the emitter-surface distance with subnanometer precision by combining atomic force and scanning tunneli...

The ordering kinetics of directed assembly of cylinder-forming diblock copolymers is investigated by cell dynamics simulation of the time-dependent Ginzburg-Landau theory. The directing field, mimicking chemically or topologically patterned surfaces, is composed of a rectangular array of potential wells which are attractive to the minority blocks. The period of the templating fields is commensu...

We consider radiative backreaction for global strings using the Kalb-Ramond formalism. In analogy to the point electron in classical electrodynamics, we show how local radiative corrections to the equations of motion allow one to remove the divergence in the self field and calculate a first order approximation to the radiation backreaction force. The effects of this backreaction force are studi...

Radiative corrections to the Casimir force between two parallel plates are considered in both scalar field theory of one massless and one massive field and in QED. Full calculations are contrasted with calculations based on employing “boundary-free” effective field theories. The difference between two previous results on QED radiative corrections to the Casimir force between two parallel plates...

A plasmon is a collective excitation of electrons due to the Coulomb interaction. Both plasmons and single-particle excitations (SPEs) are eigenstates bulk metallic systems they orthogonal each other. In nontranslationally symmetric such as nanostructures, SPEs coherently interact. It has been well discussed that SPEs, respectively, can couple with transverse (T) electric fields in systems, als...

Introduction: High field imaging (> 7 T) of deeply situated organs, like prostate, by existing stripline surface array is hampered due to insufficient B1 field and concomitant high SAR deposition. A stripline element relies on near field coupling to generate B1 field in a body. This concept has been proven advantageous as long as body areas under investigation can be positioned in the near zone...

During the past two decades, there have been tremendous developments in near-field imaging and local probing techniques. Examples are the Scanning Tunneling Microscope (STM), Atomic Force Microscope (AFM), Near-field Scanning Optical Microscope (NSOM), Photon Scanning Tunneling Microscope (PSTM), and Scanning Thermal Microscope (SThM).Results showed that the average reflectance for a dopant con...
