What about sources/devices that concentrate their radiated energy within a volume of space rather than transmitting energy equally in all directions? Dish antennae, antenna arrays, and lasers are good examples of such sources. How vulnerable are these to interception based on their limited physical ...
In recent years, domain decomposition method (DDM) has been successfully applied in real life electromagnetic examples. Especially, DDM is a very efficient method for analyzing large finite periodic structures such as finite antenna arrays or metamaterials since it is very simple to take advantage of...
Some reported examples of electromagnetic incompatibility are: 1. New electronic push-button telephones installed near the Brookmans Park medium wave transmitter in North London were constantly afflicted with BBC radio programs. 2. Mobile phones have been found to interfere with the readings of certain...
Consulting an accredited EMC test laboratory can save much time and effort in determining the appropriate test standards and requirements for general or specific products and applications.The following are the major EMC regulation agencies and examples of some of their basic, product, product family, ...
Compliant mechanisms can be found in everyday objects such as the single-piece plastic hinges in packaging as well as common all-metal binder clips. Outside of these simplified examples, why are compliant mechanisms desirable? For starters, compliant mechanisms can be made from a single material ...
In our daily lives, we can see examples of electromagnetic theory everywhere. Take a microwave oven, for instance. It uses electromagnetic energy to heat up our food. The microwaves create a special kind of electric and magnetic field inside the oven that makes the water molecules in the food...
Electromagnetic (EM) imaging aims to produce large-scale, high-resolution soil conductivity maps that provide essential information for Earth subsurface ex

Figure 22.2 illustrates a well-established EM spectrum in wavelength and frequency with graphic examples illustrating the scale of the wavelength. Each segment of the spectrum has its own properties, such as resolution and penetration depth: both are a function of the wavelength. As the frequency ...
