Dye Sensitized Solar Cells Sensitization with a Bodipy-Porphyrin Antenna System
FREE-DOWNLOADCY Lee… – Langmuir, 2009 Dye-sensitized solar cells (DSSCs) have received considerable attention as a low cost alternative to conventional silicon based solar cells.(1) These photoelectrochemical cells employ molecular dyes to sensitize high-surface area, mesoporous photoelectrodes consisting of
UWB circular slot antenna provided with an inverted-l notch filter for the 5 GHz WLAN band

The integration on this antenna of a notch filter, to reduce the possible interferences with the 5 GHz WLAN communications, has been discussed in detail. Four different
Multi-antenna based spectrum sensing for cognitive radios: A GLRT approach
FREE-DOWNLOADR Zhang, T Lim, YC Liang… – … , research Transactions on, 2010 – Abstract—In this letter, we propose multi-antenna based spec- trum sensing methods for cognitive radios (CRs) using the generalized likelihood ratio test (GLRT) paradigm. The proposed methods utilize the eigenvalues of the sample covariance matrix of the received signal vector from
