High spatial resolution, narrow band, infrared line images and CO (1—0) mm interferometer data are presented for NGC 7027. These data trace emission from the central H II region (Bra), the intermediate photodissociation region [H2 1—0S(1) and 3.3 /im dust feature], and the molecular circumstellar envelope [CO (1—0)]. The H II region lies in a cavity in the CO envelope, and consists of a smooth ...

Domain wall dynamics in thin magnetic films with perpendicular and in-plane anisotropy is studied using a novel magneto-optical Kerr effect susceptometery method. The method allows for measurements of domain wall motion under ac field excitation and the analysis of dynamic modes as a function of driving frequency and magnetic field amplitude. Domain wall dynamics in the perpendicular anisotropy...

In this work a generalization of the approach allowing time-domain (TD) excitation and fluorescence data to be generated using a finite element model (FEM) is introduced. This new functionality allows simulation of temporal pointspread functions (TPSF) for a heterogeneous scattering and absorbing media of arbitrary geometry. In the first part of this paper, the approach used to develop a comput...

The emission of light from whispering-gallery modes excited in microscopic spheres is examined. An evanescent wave is produced by total internal reflection of an optical beam at a planar glass-air interface. This evanescent wave is used to excite whispering-gallery modes in single microscopic spheres placed behind the glass-air interface. The intensity of light emitted into the air half-space f...

Multiphoton absorption induced luminescence (MAIL), as a nonlinear optical feature of noble metallic nanoparticles has shown great advantages in the in situ detection of gold nanoparticles (AuNPs). Selection of excitation wavelengths to yield high efficient MAIL signal from different sized AuNPs is of great significance, but a systematical study of this aspect is still lacking so far. In this c...
