This provides extremely low propagation loss to a receiver in the channel.
2.
Builder models communication & radar systems by calculating one-way and two-way RF propagation loss.
3.
Beyond 3 meters propagation losses indoors can increase at up to 30 dB per 30 meters in dense office environments.
4.
However, these guides suffer significant propagation loss because of the presence of metal as part of the guiding structure.
5.
This effect, combined with the free-space r " 2 propagation loss to a r " 4 propagation loss.
6.
This effect, combined with the free-space r " 2 propagation loss to a r " 4 propagation loss.
7.
Since the signal going to the target and returning had a propagation loss proportional to the range raised to the fourth power, a powerful transmitter and large antennas were required.
8.
The airborne experiments were aimed at recording quantitative data about the directivity and propagation loss of both the ultrasonic carrier and demodulated waves, rather than developing the capability to reproduce an audio signal.
9.
Many other practical design benefits include broader photonic bandgaps in diffraction based propagating waveguides and reduced bend losses, important for achieving structured optical fibers with propagation losses below that of step-index fibers.
10.
The fields associated with the surface wave along the conductor are significant out to many conductor diameters, therefore metallic or even dielectric materials inadvertently present in these regions will distort the propagation of the mode and typically will increase propagation loss.
