This article explains the operation of a balun that transforms an unbalanced antenna structure into a balanced one.

In this article, the author will identify two major types of single-conductor structure resonances and describe some case studies for both. He will then describe how design projects can quickly and easily be ‘de-risked’ from the possibilities of suffering either type of resonance by the use of low-cost field and circuit simulators and/or low-cost bench testing on physical ‘mock-ups’.

The use of chemical substances and their potential impacts on human health and the environment is a concern world-wide. This paper looks at substances and substance restrictions, why they are restricted, and how they affect the safe use and disposal of electrical, toy, and medical products.
