| Abstract(in English) | Optically induced plasma,whose density is reduced exponentially from the surface of the semiconductor,works on microwaves as a matched termination.In this report,this effect is applied to a mode filter which is constructed by the dielectric slab waveguide having periodic strip metals on the slab,and plasma is induced between these strips to absorb the TM mode fields.From the theoretical results analized by the boundary element method,the attenuation constant of TM mode is 7 times larger than that of TE mode at the plasma density of 10^16>£cm^-3>!.Further,as the plam sa absorbs the unwanted radiation,this filter has an advantage that the interference to other instruments can be reduced. |
