Embodiment 1

[0083] The top cover of the transparent cavity 4 opens

[0084] Open electromagnetic radiation, the laminar flow height of the smoke feather flow is lowered, and the width of the smoke gas stream has also increased significantly; turn off electromagnetic radiation, and smoke is quickly returned to its initial height, and the result is Figure 6 Indicated. Figure 6 (a) the smoke feather flow before the electromagnetic radiation is opened. Figure 6 (b) In order to open a smoke feather flow after radiation. Figure 6 (c) For the smoke air flow 2 seconds after the radiation is again closed. The white light column is for illumination. Figure 6 (b) The red dot on the microwave leak detector indicates an electromagnetic wave. The change in the height of the smoke feather is changed with time. Figure 8 (a) shows that the X-axis and the Y-axis are displayed in time (S) and laminar flow height (cm), respectively. Before the electromagnetic radiation is opened (B-W, square), when the electroma...

Embodiment 2

[0086] Transparent cavity 4 top cover close

[0087] When the top cover is closed, the experimental cavity 4 is completely closed. The weak flow field instability caused by the concentration difference caused by the smoke and the surrounding air causes the weak disturbance in smoke, resulting in weak oscillation of the firing at the original laminar flow and causes the smoke gas stream to enter the transition state. As the smoke is constantly incurred, the concentration-related interference is gradually reduced, and the smoke gas flow slowly returns to a stable laminar flow. When its flow state is stable, electromagnetic radiation is opened, causing serious irregular oscillations in the smoke gas stream and generating a turbulence state that is easier to maintain in the presence of electromagnetic waves. As with the previous experiment, when the radiation is present, the smoke feather air flow becomes very wide, and when the radiation is closed, the smoke feather air flow quickly ...

Abstract

The inventors of the present invention have discovered that electromagnetic waves can affect the rising form of smoke in the air, and based on this, provide an electromagnetic wave induction device using smoke instead of an antenna and a switch using the induction device. The invention uses smoke to realize the induction of electromagnetic wave signals, replaces the antenna as a receiving device, is not easily affected by the environment, can be applied to occasions where the antenna is limited, reduces potential safety hazards caused by the antenna, and can be recognized by the naked eye and intuitively read Signal conversion to realize the visual induction of electromagnetic wave signals. Compared with the traditional electromagnetic wave induction device, the present invention provides a brand-new electromagnetic induction device, the antenna of the receiving part is replaced by the smoke in the experimental cavity, and the smoke directly exists as a signal receiving device, which overcomes the existing technology Antenna constraints.

Description

Technical field [0001] The present invention belongs to the field of electromagnetic wave sensing, and more particularly to an electromagnetic wave sensing device and a switch to which the device is applied. Background technique [0002] Electromagnetic wave, is a oscillating particle wave that is derived from each other and vertically and the magnetic field in space, which is propagated in the electromagnetic field propagated in the form of fluctuations, has a wave binarony, and electromagnetic wave is oscillated and perpendicular to each other and vertical electric fields and magnetic fields. Move in the form of waves. Electromagnetic radiation is mainly divided into high frequencies from low frequencies, radio waves, microwaves, infrared, visible light, ultraviolet rays, X-rays and gamma rays. Wireless waves are used in communication, etc., microwaves are used for microwave ovens, satellite communications, etc., infrared for remote control, thermal imager, infrared guided miss...
