摘要： Systems and methods for detecting low-loss eigenmodes of a spherical waveguide bounded by the Earth's surface and its ionosphere are disclosed. One or more eigenmodes of the Earth- ionosphere waveguide may be computed (1404) based on a mathematical model incorporating electrical properties of the terrestrial surface and plasma physics of the ionospheric layer. A transmitter apparatus may be used to transmit (1402) electrical power into the Earth-ionosphere waveguide in the form of an electromagnetic wave, which may, in turn, be detected (1406) by a receiver apparatus remote from the transmitter apparatus. A coupling strength between the transmitted electromagnetic wave and the one or more eigenmodes may be determined (1408) by measuring power received by the receiver apparatus in the detected electromagnetic wave. By iteratively adjusting parameters of the transmitter apparatus, determining the coupling strength, and refining a quantitative description of the eigenmodes, the eigenmodes may be harnessed for wireless power transmission throughout the Earth-ionosphere waveguide.

摘要： Bandwidth of a test channel is determined from a single port Time Domain Reflectometer (TDR) measurement with the channel terminated in a short or an open circuit. Bandwidth is estimated by: (1) making a TDR measurement of a channel terminated in a short or open circuit; (2) determining a maximum slope of the reflection from the TDR measurement; (2) calculating an interpolated rise or fall time, for example by taking 80% of the applied voltage between the 10% and 90% points, and then dividing the applied voltage by the maximum slope determined; (3) dividing the overall interpolated rise time by the square root of two to account for the TDR signal proceeding through the channel twice; (4) removing the contribution of rise time from measurement equipment; and (5) completing calculation of channel bandwidth using a formula to relate bandwidth to rise time, such as: bandwidth = .35/rise time.
