Hierarchical Multiple Bit Clusters and Patterned Media Enabled by Novel Nanofabrication Techniques - High Resolution Electron Beam Lithography and Block Polymer Self Assembly
Diblock copolymer E-beam lithography Magnetism Multiple state cluster Nanofabrication Self assembly
2014/11/20
This thesis discusses the full scope of a project exploring the physics of hierarchical clusters of interacting nanomagnets. These clusters may be relevant for novel applications such as multilevel da...
Active Negative Index Metamaterial Powered by an Electron Beam
Active Negative Index Metamaterial Electron Beam Optics
2012/5/17
A novel active negative index metamaterial that derives its gain from an electron beam is intro- duced. The metamaterial consists of a stack of equidistant parallel metal plates perforated by a period...
An X-Ray Free Electron Laser Oscillator with Intermediate Energy Electron Beam
X-Ray Free Electron Laser Oscillator Intermediate Energy Electron Beam
2011/8/4
Abstract: Harmonic lasing of low-gain free electron laser oscillator has been experimentally demonstrated in terahertz and infrared region. Recently, together with the high-reflectivity high-resolutio...
Radiative instability of a relativistic electron beam moving in a photonic crystal
Radiative relativistic electron beam photonic crystal
2010/11/16
The radiative instability of a beam moving in a photonic crystal of finite dimensions is studied. The dispersion equation is obtained. The law $\Gamma\sim \rho ^{1/\left( {s + 3} \right)}$ is shown to...
Axial electric wake field inside the induction gap exited by the intense electron beam
linear induction accelerator induction gap wake field high voltage breakdown property
2009/8/17
While an intense electron beam passes through the accelerating gaps of a linear induction accelerator, a strong wake field will be excited. In this paper a relatively simple model is established based...
