plimph said:Can radio waves propagate through the walls of a solid steel (1/2" wall thickness) box that completely encloses the RF transmitter? Do lower frequencies work better? Any insight would be great. I'm a newbie her, so please be gentle.
RF penetration through metals occurs when radiofrequency (RF) waves are able to travel through a metal material without being significantly attenuated or blocked. This is possible because the metal material has a low resistance to the flow of electromagnetic energy, allowing the RF waves to pass through without being absorbed or reflected.
The penetration of RF waves through metals can be affected by several factors, including the frequency and power of the RF waves, the type and thickness of the metal material, and the distance between the RF source and the metal surface. Higher frequencies and powers, as well as thinner metal materials, generally result in better penetration.
No, not all types of metals can be penetrated by RF waves. Metals with high electrical conductivity, such as copper and aluminum, are more easily penetrated by RF waves compared to metals with lower electrical conductivity, such as iron and steel. Additionally, thicker metal materials may be more difficult to penetrate compared to thinner materials.
Yes, there are safety concerns when working with RF penetration through metals. Exposure to high levels of RF waves can potentially cause harm to human health, including thermal burns and tissue damage. It is important to follow safety guidelines and regulations when working with RF waves to minimize any potential risks.
RF penetration through metals has various practical applications, including communication systems, medical treatments, and industrial processes. For example, RF waves can be used to transmit signals through metal barriers for wireless communication, or to heat and melt metal materials in industrial processes. In medical treatments, RF waves can be used for imaging and therapy.
