摘要：
We consider two types of near-field microwave imaging probes. One employs the small circular ridged aperture and the other employs unsymmetrical transmission cavity whose closed ends comprise the small circular aperture with no ridge and capacitive iris of double ridge type which is placed half waveguide wavelength apart from the circular aperture. The relationship between working principles of the two types of probes is discussed in both transmission efficiency through a small aperture and spatial confinement of the electromagnetic energy.
