The full form of RF is Radio Frequency. The radio frequency (RF) measurement represents the oscillation rate of electromagnetic radiation, or electromagnetic radio waves, with frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz).

As a radio wave travels from the transmitting to the receiving antenna, it may be disturbed by reflections from buildings and other large obstacles. Disturbances arise when several such reflected parts of the wave reach the receiving antenna and interfere with the reception of the wave.

Radio waves can be shielded against by a conductive metal sheet or screen, an enclosure of sheet or screen is called a Faraday cage. A metal screen shields against radio waves as well as a solid sheet as long as the holes in the screen are smaller than about 1⁄20 of wavelength of the waves.

The two most common causes of interference are transmitters and electrical equipment.

You can enable and disable the radio button by using the disabled property of HTML DOM. Set this property to true (disable=true) to disable the radio button in JavaScript.

The common metal RF shielding materials are copper, aluminum, nickel silver, pre-tin plated steel, and Mu-metal. Elastomers and textile fibers can also be used as an RF shielding material by making them conductive first by adding metal fillers and coating.

A magnet has its own magnetic field which disturbs the magnetic waves of radio waves. However these interruptions doesn't alter the wave but simply superimpose it. Hence the effect is seen only near the magnet.

Steel is another commonly used metal for RF shielding. Although, steel-based alloys show magnetic field shielding capability, this type of shielding doesn't offer as high of attenuation as copper and aluminum can.
