Microwaves & RF Magazine (May, 2009)- Article-- "Coaxial cables have long been thought to support only a single transverse-electromagnetic (TEM) propagation mode. But a solution to the Maxwell-Heaviside equations supports the existence of a propagating transverse-magnetic (TM) surface-wave mode as well. Until the present day, this mode has generally gone unnoticed and no practical way to implement structure using it was known. The mode is suppressed by the outer conductor in coaxial cables of conventional impedance, but is dominant in higher-impedance coaxial cables and also is supported by a single uninsulated and unconditioned conductor having no outer shield. This non-radiating surface-wave mode, which has great practical use at RF through microwave frequencies, can exhibit very low attenuation and a relative propagation velocity of unity. This first installment of a three-part article will introduce this surface-wave mode. Later installments will further describe the mode and describe some applications using overhead power distribution lines for last-mile communications applications."

Computing Unplugged Magazine (August, 2006)- Interview-- "Corridor's technology, although providing very high rate information transfer over powerlines is by no means conventional "access BPL" as described by the FCC." Read the interview...

Computing Unplugged Magazine (August, 2006)- Understanding the information rate of BPL and other last-mile pipes-- "Throughout our research into BPL, we've talked about interference issues. In his in-depth interview, elsewhere in this issue, Glenn Elmore introduced the question of data rate across the various technologies. In this short, highly technical article, he shows how that data rate applies over a variety of "last-mile pipes"." Read the article...

Telecom Magazine- Filling cellular holes with power line technology-- "Broadband Power Line (BPL) technology developer Corridor Systems is working on a way to use its high-speed data over power lines concept to extend and strengthen cell phone networks. Specifically, Corridor, a 3-year-old Santa Rosa, Calif. company, believes its gear can be used to transport cell signals over medium power lines into hard-to-reach cellular dead zones where it can be offloaded from the power grid via small pole- or wire-mounted antennas."
