Time-Domain Analytical Expression for Near Fields of Arbitrarily Oriented Electric Dipole and Its Application

الملخص EN

The near fields of electric dipole are commonly used in wide-band analysis of complex electromagnetic problems.

In this paper, we propose new near field time-domain expressions for electric dipole.

The analytical expressions for the frequency-domain of arbitrarily oriented electric dipole are given at first; next we give the time-domain expressions by time-frequency transformation.

The proposed expressions are used in hybrid TDIE/DGTD method for analysis of circular antenna with radome.

The accuracy of the proposed algorithm is verified by numerical examples.
