โฆ Synopsis
The unit vector s was chosen arbitrarily, and ห0 z f L. The precision was set to 1.0 = 10 y3 . For each L, the function T was evaluated at 2 L 2 observation points. This is L in accordance with the demands of MLFMA. The results are presented in Table 2.
In the table, entries marked ''direct'' refer to the direct ลฝ .
2 evaluation of Eq. 1 at 2 L points, and those marked ''fast'' refer to the corresponding requirements for the algorithm presented in this paper. Note that, since the translation operators are almost always stored, there is no evaluation time reported for the direct approach.

In this Letter we suggest an iteratii:e imaging technique based on a simulated annealing (SA) algorithm for a perfectly conducting cylinder. It is numerically shown that an imaging technique that uses SA does not require prior knowledge regarding the center and the shape of an object9 whereas one th
