Researchers have discovered a novel mechanism through which information can be effectively transmitted across many areas in the brain -- a finding that offers a potentially new way of understanding ...

Figure 3. Single- and three-mode propagation in optical fibers. Single-mode longer wavelength signal can only propagate in a single-mode but a shorter wavelength signal can propagate in three-modes.

The author is senior engineer at Cavell, Mertz and Associates Inc. When we say “propagation software,” we refer to models that run pathloss (signal propagation) studies, as distinguished from the ...

Electronic engineers, both digital and analog, must now understand how to live with transmission lines. Behind the need for improved understanding are today's ICs, which produce signals that rise and ...

Part 1 of this series described how digital signals propagate through PC boards [Refs. 1, 2, 5, 6]. In part 2, we look at specific board designs to achieve low EMI. The biggest issue I see in my ...

Radio waves should really be called electromagnetic or EM waves simply because they consist of a magnetic field and an electric field. A signal from a transmitter applied to an antenna generates the ...

Interference-free GNSS signals are essential for more than just military vehicles and aircraft. Anti-jam systems usually suppress signals from interference sources by means of spatial filtering. These ...
