METAL AND METALLIC OBJECTS

AND ELECTROMAGNETISM

Some “experts” claim it is helpful to place metallic objects in rooms with high radio frequencies to reduce exposure. All materials absorb radio frequencies to some extent, but all metals are also conductive and reflect radio frequencies, too.

With a hyper-logarithmic antenna and a spectrum analyzer, you could see that metallic objects and even partially painted rooms with RF-shielding paint will usually increase the power density measurements of RF, the reflection rate, and the co-signaling interference.

Adding metal or partial RF shielding can increase high-frequency noise by causing multi-path interference and standing waves.

A standing wave is created when an incident wave and the reflection wave collide. A standing wave often has a higher voltage amplitude than the incident wave (the initial wave you are trying to block), also producing additional air-borne harmonic transients.

Further, simply adding a large metal shield in a room that is not bonded is a potential hazard if lightning were to strike your home.

Fractals from standing waves are created when an incident and reflection wave collide.

Some truth regarding studies:

1) There are various ways to interpret physical phenomena, experimental results, and data once a test has been conducted.

2) Even the most intelligent PhDs make fundamental mistakes, primarily when operating outside their expertise.

Because RF is electromagnetism, metallic objects, iron, in particular, will fill the core of the solenoid effect of RFR and amplify the intensity. This is how and why electromagnets can be hundreds of times more powerful once an iron core is inserted inside a solenoid coil. 

Please, see the diagram: Iron Core Solenoid

 A Step-up core transformer can exponentially increase voltage.
