Stopping the Flow of RF Currents In A Conductor. Part 2, Filtering

When there are unwanted RF currents (cell phone radiation) flowing in a conductor, filtering can be used to stop that flow. This is not the best approach to reduce any danger, but will be described in this article.

The intention of this article is to address the case of RF current flowing through an ear piece wire that is going from a cell phone on a person's hip to the ear piece in their ear, bringing about safety and health concerns.

A reasonable analogy for a filter is when a dam is placed on a river. The dam stops the rivers flow. It holds it back. It is important to note here that the pressure of the river is always there and the river is, in some way, trying to get through.

An electrical filter is quite similar. The filter stops the flow of the unwanted currents, to a greater or lesser degree, but the voltage (the push of the electricity) is always there, trying to get through. In the case of high performance filters, this can sometimes lead to other problems, such as the development of high voltages.

In the next article we will discuss the approach of dissipation of the unwanted cell phone radiation through the use of a cell phone accessory, the Noble1 divice..
