Abstract

It is proposed to form periodic structures from solenoids in order to control their microwave frequency dispersion by a magnetic field. It is experimentally shown that, using an external 0.05-T magnetic field, one can change the frequency of fixed effective refractive index of a 2D photonic crystal consisting of solenoids with a factor of 6 GHz T^–1. Applying a magnetic field, one can also control the divergence of the microwave radiation generated by a photonic crystal.

通过磁场控制二维光子晶体的频散

摘要

提出了由螺线管形成周期性结构以便通过磁场控制其微波频率分散。实验表明，使用外部0.05-T磁场，可以以6 GHz T ^–1的系数改变由螺线管组成的2D光子晶体的固定有效折射率的频率。施加磁场，还可以控制光子晶体产生的微波辐射的发散。
