By following an exact analytical procedure we study the transmission properties of a network of quantum wires arranged in a so-called T3 configuration and in the presence of a perpendicular magnetic field. It is shown that proper use of a single unit cell is sufficient to demonstrate a recently discovered localization phenomenon for all wavelengths and for special values of the external field. This Aharonov-Bohm localization is shown to be independent of a vertex coupling that appears as a free parameter in the probability flux conservation. © 2002 Elsevier Science B.V. All rights reserved.
