A device and method for spatially resolved photodetection and demodulation of temporally modulated electromagnetic waves makes it possible to measure phase, amplitude and offset of a temporally modulated, spatially coded radiation field... R Lange,P Seitz - US 被引量: 216发表: 2006年 A...
摘要: Expressions are obtained for the probability of ionization of atoms and solid bodies in the field of a strong electromagnetic wave whose frequency is lower than the ionization potential. In the limiting case of low frequencies these expressions change into the well关键词:...
6). The aberration-corrected high-angle annular dark-field scanning TEM images in Fig. 2e, f and the fast Fourier transform pattern (Fig. 2f inset) confirmed that only the cubic phase of Sn with a resolved 0.201 and 0.291 nm lattice fringes existed in the Sn nanoparticles obtained by...
Here, we summarize the description in terms of the material-independent modes10 of the full-wave electromagnetic scattering by a body which occupies a domain Ω of characteristic dimension lc suspended in vacuum and excited by a time harmonic electromagnetic field with frequency ω incoming from infi...
