Constructed of carbon steel, the Dust Hound cyclone uses a specially shaped ground plate
to divert dust towards the walls and to interrupt the airflow, creating a very localized pressure drop that causes more particulate to fall out of the airstream and reduce dust re-entrainment.
The ground plate
features a rectangular shape with dimensions of 9.7x9 [mm.sup.2].
Both the top-patterned copper and bottom ground plate
are 0.035 mm thick with an electric conductivity of 5.8 x [10.sup.7] S/m.
It is separated from a ground plate
, by a distance [d.sub.1].
Its metallic shell and ground plate
provide a minimum impedance to ground and higher performance than a PCB-mounted filter, and provides more consistent pinto-pin performance.
To avoid the effects of the nozzle boundary layers on the aerodynamics of the car models, a ground plate
with a length of 4.4 m is installed in the measurement section at a height of 0.66 m from the wind tunnel floor.
It consists of a dual-band feeding antenna in the center, four dual-band RFSRs on the side walls, and a finite-square ground plate
on which the feeding antenna and RFSRs are perpendicularly mounted.
1, where perfectly sharp border between the transmission line and the ground plate
is seen .
In this design, electromagnetic fields are transferred through a ring microstrip into a small air gap (approximately 500 microns) by connecting a microwave input source to an SMA connector on the microstrip and ground plate
. Teflon will be used as the dielectric substrate and copper will be used to create the microstrip.
Soft AC is the voltage that produces soft electrostatic forces in the system; that is, it produces small to very small amplitudes (with respect to the gap between EA-MEMS-CR and the ground plate
) when the frequency is away from resonance zones.
To make a ground plate
, start with a clean, bare steel plate or sheet that's 1/4 inch thick.
