Abstract :
A modified image method for calculating the fields produced by straight electric and magnetic current segments is proposed and found to be effective for calculating the fields near the source. Computing errors of the field increase as the distance from the source to the observation point increases. Therefore, the modified image method is improved for the accurate calculation at any position by adding a correcting term. In order to check the adequacy and usefulness of the method considering the term, its error is compared with that of the method without it
