E. Kiesewetterhe coaxial line, rectangular and circular waveguides, stripline, and microstrip. A characteristic of each of these structures is that it will support a set of modes, usually described as consisting of two subsets: TE (transverse electric) and TM (transverse magnetic).

M. Fischergh the aperture and rays diffracted by the aperture edges. Its origins can be traced to the early ideas on optical diffraction of Young as more recently formulated by Keller in his geometrical theory of diffraction. It is particularly useful in deriving the radiation pattern in the lateral and rear directions and is described in Chapter 4.精确 发表于 2025-3-23 09:25:44
L. Stockingerd cheaper to construct periodic than aperiodic arrays. Aperiodic arrays, treated in the next chapter, have advantages in high-resolution thinned configurations, and when used to achieve equivalent amplitude taper without the use of a complex feed network.
