MRI measurements were performed using a horizontal bore 9.4 T Bruker/Magnex system, equipped with a home-built rat head surface RF transmitter and receiver coil, approximately 30 mm in diameter.
Figure 1 presents the experimental layout of our STBEM survey, which uses many surface EM transmitters in different directions as well as borehole EM transmitters.
Ultrasound topometry is a measurement for assessment of motion analysis system based on surface mounted transmitters in a three-dimensional space and it was carried out with the CMS 20 measurement system (Zebris Medical GmbH, Isny, Germany).
In conditions of high frequency, the current gradually concentrates on the surface of the transmitter coil and the internal current of the transmitter coil is obviously decreased.
When phones and laptops are placed on an eCoupled surface, the power transmitter in the work-surface detects the resonant circuit in the device's receiver, which then tells the transmitter how much power to send.
(The transmitters, which cost about forty-five hundreachollarsendch, signalsgnals to a satellite when the animal is on the surface. The transmitter falls off when the animal molts).
(The line is needed because the sharks themselves rarely break the surface, and the transmitter cannot signal to the satellite from under water).
More also, the ratio of the nanopores footprint ∂ N to transmitter surface area ∂Ω should be unity.
That is to say, the maximum current density is distributed at the surface of the transmitter coil.
The nanopores are formed by perforating the surface of the transmitter, and through these nanopores, the molecules emitted from the point source transude as shown in Fig. 3.
Since the practicality of ∂Ω/∂ N = 1 is technically unrealistic in this case, we have to include in the model the possibility of some of the diffusing molecules at an arbitrary time t being reflected back at some boundary points on the transmitter surface.
