EFFECT OF LOSS ON DIRECTIVITY ENHANCEMENT OF LINE SOURCE RADIATION BY LEFT-HANDED MATERIAL

摘要：

We have investigated radiation of a line source within a hollow cylinder made of left-handed materials (LHMs).We find that the LHMs cylinder functions directivtty enhancement of source radiation. However,electromagnetic loss can degrade the enhancement effects. By comparing the effects of electric and magnetic losses,we find that magnetic loss is a main issue and should be minimizedInorder to get better directivity enhancement effect.
