Principle of radiation protection cap

Silver fiber refers to a composite fiber formed by infiltrating nano-silver ions into nylon fibers. The loop formed by silver
fibers in the fabric generates an induced current, and the induced current generates a reverse electromagnetic field for
shielding. Silver has a good conductor that can reflect electromagnetic waves, that is, when the aperture of the metal mesh is
less than 1/4 of the wavelength of the electromagnetic wave (wavelength = speed of light/frequency), the electromagnetic wave
cannot pass through the metal mesh, which plays the role of shielding electromagnetic waves.
