Popis:	The physics of the soft-X-ray whispering gallery is outlined with emphasis on the delivery of circularly-polarized radiation in the photon energy range h ω = 10–180 eV . Calculations of the relevant figure of merit TP2 (T = transmission, P = polarization) for candidate materials reveal exceptionally high efficiency for Rh (maximum TP2 = 56% at h ω = 105 eV ) and for Ag (44%, 125 eV). The practical implementation of a whispering gallery is discussed and compared with a 4-reflection device. The former offers high efficiency with narrow band pass (∼ 30%); the latter offers reasonable efficiency (TP2 = 4–28%) over an extended ħω range (10–150 eV).
