摘要

本文给出了赫兹偶极子的时域辐射场的精确推导。通常的频域偶极子场的推导忽略了偶极子上的相位变化,因此,它是不精确的。这里给出的时域推导不涉及任何近似。利用偶极子长度趋近于零时精确场表达式的极限,研究了极小偶极子时域场与频域场的关系。

An exact time domain evaluation for radiated fields from a Hertz dipole
This paper provides an exact derivation of the radiated fields of a Hertz dipole in time domain. The usual derivation of the frequency domain dipole fields involves neglecting the phase variation across the dipole and hence, it is not exact. The time domain derivations presented here do not involve any approximations. The relations between time domain and frequency domain fields of an infinitesimal dipole are studied by taking the limit of the exact field expressions as the dipole length goes to zero.
