A　single-source　surface　integral　equation　(SS-SIE)　for　transverse　electric　(TE)　scattering　from　cylindrical　multilayered　objects　is　proposed　in　this　article.　By　incorporating　the　differential　surface　admittance　operator　(DSAO)　and　recursively　applying　the　surface　equivalence　theorem　from　innermost　to　outermost　boundaries,　an　equivalent　model　with　only　electric　current　density　on　the　outermost　boundary　can　be　obtained.　In　addition,　an　integration　approach　is　proposed,　where　the　small　argument　expansion　of　the　Hankel　function　is　used　to　evaluate　the　singular　and　nearly　singular　integrals.　Compared　with　other　SIEs,　such　as　the　Poggio-Miller-Chang-Harrington-Wu-Tsai　(PMCHWT)　formulation,　the　computational　expenditure　is　reduced　for　multilayered　structures　because　only　a　single　source　is　needed　on　the　outermost　boundary.　As　shown　in　the　numerical　results,　the　proposed　method　generates　only　19%　of　unknowns,　uses　26%　of　memory,　and　requires　29%　of　the　CPU　time　of　the　PMCHWT　formulation.　©　1963-2012　IEEE.
