capacity of the multiple-antenna wiretap channel
FREE-DOWNLOAD T Liu… – Information Theory, research Transactions on, 2009 Abstract—The secrecy capacity of the multiple-antenna wiretap channel under the average total power constraint was recently characterized, independently, by Khisti and Wornell and Oggier and Hassibi using a Sato-like argument and matrix analysis tools. This paper presents an .
Cross resonant optical antenna
FREE-DOWNLOAD P Biagioni, JS Huang, L Duò, M Finazzi… – Physical review letters, We propose a novel cross resonant optical antenna consisting of two perpendicular nanosized gold dipole antennas with a common feed gap. We demonstrate that the cross antenna is able to convert propagating fields of any polarization state into correspondingly polarized,
