Abstract: A new version of the regime of electron trapping is proposed for gyro-amplifiers. The use of this regime in the cyclotron resonance maser with a weakly relativistic electron beam can ...

On the other hand, the size of a nonresonant FSS array element is usually large. A new miniaturized FSS capable of exhibiting a second-order bandpass response is proposed in this letter. Two ...

In this paper, we investigate the evolution of TNOs in each of Neptune's n:1 resonances between the 3:1 and 14:1. We conclude that both resonant and nonresonant objects beyond the 12:1 near similar to ...

引言你是否曾惊叹于荧光显微镜下那些被点亮的生命图景？通过各种荧光染料或蛋白，我们得以窥见细胞的结构、蛋白的位置，仿佛给生命穿上了五彩的外衣。荧光显微镜无疑是现代生命科学的基石。然而，这层“外衣”有时也会带来烦恼。给分子打上荧光标签，就像给它们背上一个 ...

Together with tunneling and entanglement, coherence belongs among the hallmarks of quantum mechanics and among the prerequisites for building quantum devices. In attochemistry, the loss of electronic ...

One of the most important features of nonlinear systems with several degrees of freedom is the presence of internal resonances at certain relations between natural frequencies of different modes. This ...
