Smith-purcell radiation by a periodic strip grating over a grounded dielectric slab

접지된 유전체층 위의 주기적인 스트립격자에 의한 smith-purcell 복사

The problem of Smith-Purcell radiation by a strip grating over a groundeddielectric slabl is analyzed by use of the equivalence principle, Floquet's theorem, and the method of moment. the relative radiation intensities of the space harmonics, computed by use of the proposed method, for the appropriately chosen charge velocities and grating dimensions are presented. In particular, some relationships between the smith-purcell radiation and the leaky-wave radiation in the proposed geometry are investigated.
