The pure solubility of graphite cold iron triangle is higher than the stability of ceramic triangular plate, so in terms of mass distribution, the two are similar

In the middle and high frequencies, the iron strike sound you see is the electromagnetic wave absorbed by the absorbing material. For low frequencies, the graphite sheet actually absorbs a wider range of frequencies. Electromagnetic waves propagate in graphite in units of usb, high frequency can act on high-power devices, and low frequency can act on devices that have no effect on wide frequency. In my opinion, led is to extract a frequency band of the usb interface signal for use. It's like no matter how powerful a person is, he can't change his family. This is the reason.

The strength of metal materials depends on the energy loss of electromagnetic waves, so it is necessary to reduce the energy loss of the material as much as possible. At the interface where the electromagnetic wave works, the energy loss of the electromagnetic wave is much smaller than the energy loss in the interface. The graphite plate is interposed between the medium interface and the medium, which can greatly reduce the energy loss. In general, there are cold iron triangular structure and silicon iron triangular structure. The contact area between metal and non-metal materials is an important factor in determining the quality of contact. Generally speaking, non-metal materials have better corrosion and oxidation resistance.

Different device sizes determine different sensitivities to energy loss, so some wide-amplitude high-frequency waves will lose a lot of energy when accommodating devices with high energy, while small devices can accept and receive lossless energy with narrow wavelengths without damage . In the intersection of multiple types of devices, it is the influence of body shape. My own speculation: the contact area will have an impact on impedance, reflection, vibration, and electromagnetic compatibility.

1. The material itself has radiation properties because of energy loss;

2. The energy of the current amorphous silicon-titanium nitride will be reduced;

3. A certain level of electromagnetic field is required;

4. The most important factor of the electromagnetic field is its own power factor, so the part with insufficient magnetic field will be compensated with a large reaction resistance in the switching circuit of the external circuit; similarly, the part with too small reaction resistance can be compensated with a large reaction capacitance .
