用于光钟的表面等离激元磁性器件设计

摘要

In the field of precise measurement for time,an ultra-cold atom optical lattice clock has the best accuracy and stability,in which the magnetic device is very important.For the practical need of miniaturization on the basis of optical clock system,by using the enhance effect of surface plasmon act on the local electromagnetic field,we designed a micro magnetic devices,and made the theoretical analysis and numerical simulation of electromagnetic properties of the device.%在时间的精确测量领域，超冷原子光晶格钟具有最佳的精确性和稳定性；其中的磁性器件至关重要。本文依据光钟系统微型化的切实需要，利用表面等离激元效应对局部电磁场的增强效应，设计了微型磁性器件，并对器件的电磁性能做了理论分析和数值模拟。
