摘要

本文研究了从一个径向电偶极子到一个腐蚀栅极球表面的辐射。结果表明，在给定模式下的功率取决于表面电抗和球面周长。事实上，对于这些参数的某些值，特定的模态被强烈激发并包含了大部分的功率。这种结构可以看作是一个外腔谐振器，其谐振特性是周围介质折射率的函数。这开启了一种可能性，即表面波球形反射器可能在所有国家的反射中有重要的应用。

Resonant characteristics of a corrugated sphere

The radiation from a radial electric dipole on t he surfacc of a corru gatcd sphcrc is treated . It is shown t hat t he power ra di ated in a given mode depends crit ically on t he surface reactance a nd t he circumference of t he sphere. In fac t, for certain values of t hese pa rameters, particular modes a re strongly excited and contain most of t he powcr . Such a structure can be regarded as a n extern al reso nator an d its resonan t characte ri stics are a function of the refractive index of th e surroundin g medium. This opcns t he possibility t hat a surface-wave spherical reso nator m ay have important appli cations to refmcto llwtry.
