Electromagnetic Spectrum - Wavelengths

"Some insects, like bees, can see light of shorter wavelengths than humans can see."

This is something to Buzz about. This chart is excellent, a Pictogram. A small image with a Graphical, Complete and Concise expression of a Scientific Truth.

Electromagnetic Spectrum - Berkeley Lab

Radiation is energy that travels and spreads out as it goes-- visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays.....

Electromagnetic Spectrum

Measuring the electromagnetic spectrum

Faraday cages are structures - as small as a shoebox or as big as a building - that protect what's inside from surrounding electromagnetic radiation (EM).

RF circuit design - theory and applications

The objective of this textbook is to develop the RF circuit design aspects in such a way that the need of transmission line principles is made clear without adopting an electromagnetic field approach. Therefore, no EM background is necessary beyond a first year undergraduate physics course in fields and waves as provided by most colleges and universities. Students equipped with the knowledge of basic circuit theory and/or an exposure to microelectronics can use this book and cover the entire spectrum from the basic principles of transmission .RF Circuit Design: Theory and Applications

RF Circuit Design - Theory and Applications by R.Ludwig and P.Bretchko

This practical and comprehensive book introduces RF circuit design fundamentals while emphasizing a circuit-based approach.

RF circuit design: theory and applications

Covers a number of important topics, including RF Amplifier Designs; Matching Networks; Scattering parameters; Smith Chart; Oscillators and Mixers; common filter types; the high-frequency behavior of common circuit components; the theory of distributed parameters through a discussion on Transmission Lines; and active/passive RF circuits. It also provides features to make the material easier to digest, including self-contained chapters that require only simple mathematical skills (calculus) and examples that are strategically dispersed throughout the chapter to clarify and explain the theoretical developments.

RF Microwave and Wireless Data Communication

The days of Voice Communication are coming to an end. In fact it has been happening in the background all along. It is Digital Replacing Analog Everywhere. Voice is now data. In the future Voice Communication is just an App you need to buy as an option.

Whatever the struggle between technologies, The future communications will be just Broadband Wireless Devices with Voice, Data and Web all in one. The intermediate technologies we see today, the Transitional Technologies are part of a Large Learning Curve. The future may be more of Optics, WiMax and more like Any Device can do Anything. Not Convergence but more an Intermeshed Collage.

RF Microwave and Wireless Data Communication

This RF is also a Tough Science and needs Authentic and Highly Skilled Engineers to design and develop the technologies for the future. The Budget of the Average consumer will be less, the appetite enormous. The Business Models complex and very challenging. The customer potential is 100% and it will work only if it is affordable and planned carefully. It is not as easy as it looks.

More Reading
With the Wi-Fi and WiMAX becoming essential in Intranet and Internet Networks, and as new low power consumption tablets, netbooks and webbooks become commonplace; RF Microwave learning is important for designers.

It is almost like, every person is a potential user for a Handheld Computer. Which is not only a communicator but more important, News, Knowledge and Information is at his fingertips. This is an empowerment that makes a better worker, student, citizen or a businessman.
