The propagation loss
L (also known as path loss) is a parameter used to quantify the loss of field strength when it propagates from the transmitter to the receiver antenna.
The refractive indices were measured at 850 nm wavelength, which is the same wavelength at which the optical propagation loss
is measured for polymer waveguides.
Since the propagation loss
of radiated electromagnetic noise depends on the parasitic capacitance value, adjust the parasitic capacitance value so that the propagation loss
of radiated electromagnetic noise in the automobile test system can be realized.
(3) The propagation loss
model can be sophisticated to better reflect the particularities of other scenarios (e.g.
(2) Calculate radar electromagnetic wave propagation loss
, which is simulated as the observation value.
However, these applied polymer ring resonators are not suitable for the sensing elements of RIOGs due to the characteristics of small diameter and high propagation loss
. The polymer-based resonator used in RIOG requires a much larger diameter and a lower propagation loss
because the performance of gyroscope mainly depends on the enclosed area and the propagation loss
of the waveguide resonator [3,19].
In the equation, the most important parameter is the propagation loss
. So we will discuss how to calculate it.
It was demonstrated in [3, 13] that this selection significantly reduces the total propagation loss
, which consists of dissipation loss and diffusion loss.
The width of the waveguide will influence the mode of propagation thus increasing the propagation loss
. Besides, the deviation of actual waveguide structure will affect the mode of propagation.
On-body antennas also experience high propagation loss
. Thus, under all these circumstances, it is hard for the antennas attached on human body to remain operational.
Radio propagation loss
models are used in simulations to estimate the received signal strength of each packet received by a node.
