The Microwave Engineering Handbook pp Cite as. The premier applications of microwaves are presented in different chapters of this book; they are terrestrial and satellite links, radio and TV transmission Chapters , radars and remote sensing Chapter 4 , countermeasures Chapter 5 , infrared detection Chapter 6 and radioastronomy Chapter 8. Other applications also exist and present a growing interest, which are related to the so-called industrial, scientific and medical ISM applications. The corresponding processes can be easily described once several basic properties related to interactions between microwaves and different kinds of material have been brought to mind.

Microwave technology is now widely used in a variety of medical applications. Most commonly microwave energy is used to create localised dielectric heating in order to desiccate human tissue - known as microwave ablation. Common medical areas of application include:. Microwaves have played an important role in the fight against cancer, providing a new way of treating the disease. Microwave ablation is commonly used in the removal of unwanted tissue masses, for example liver tumours, lung tumours and prostate ablation and also in the treatment of large tumours. Cancer patients who are poor surgical candidates can also benefit from microwave ablation, as it is minimally invasive. A major benefit of microwave technology is flexibility - a wide range of medical applications can benefit from the range of frequencies available.
Industrial, scientific, medical and domestic applications of microwaves
Reviewed: January 8th Published: July 4th Owing to the rapid development of microwave technology, the microwave components and devices are increasingly common and relative low price compared to 10 years ago. Nowadays, microwave devices are often used and become an indispensable necessity in our daily routines, such as microwave ovens, mobile phones, and Internet. Different microwave applications and technologies will use certain frequency band to avoid frequency interference. These frequencies are grouped into several smaller bands.

Microwave processing of materials is a technology that can provide the material processor a new, powerful, and significantly different tool with which to process materials that may not be amenable to conventional means of processing or to improve the performance characteristics of existing materials. However, because it is fundamentally a new and different processing technology, it requires the materials processor to learn and understand the technology before attempting to use it. The committee found that efforts in microwave process development that succeeded commercially did so because there was a compelling advantage for the use of microwave energy. Failure almost always resulted from simple, general causes, e.

The FCC regulates radio frequency RF devices contained in electronic-electrical products that are capable of emitting radio frequency energy by radiation, conduction, or other means. These products have the potential to cause interference to radio services operating in the radio frequency range of 9 kHz to GHz. Almost all electronic-electrical products devices are capable of emitting radio frequency energy. Most, but not all, of these products must be tested to demonstrate compliance to the FCC rules for each type of electrical function that is contained in the product. As a general rule, products that, by design, contain circuitry that operates in the radio frequency spectrum need to demonstrate compliance using the applicable FCC equipment authorization procedure i. A product may contain one device or multiple devices with the possibility that one or both of the equipment authorization procedures apply.
ISM radio band
The ISM radio bands are portions of the radio spectrum reserved internationally for industrial, scientific and medical ISM purposes other than telecommunications. The powerful emissions of these devices can create electromagnetic interference and disrupt radio communication using the same frequency , so these devices are limited to certain bands of frequencies. In general, communications equipment operating in these bands must tolerate any interference generated by ISM applications, and users have no regulatory protection from ISM device operation. Despite the intent of the original allocations, in recent years the fastest-growing use of these bands has been for short-range, low power wireless communications systems, since these bands are often approved for such devices which can be used without a government license, as would otherwise be required for transmitters; ISM frequencies are often chosen for this purpose as they already have interference issues.

Откуда-то донеслись звуки песнопения. В задней части церкви между скамьями продвигался человек, стараясь держаться в тени. Ему удалось проскользнуть внутрь в последнюю секунду перед тем, как дверь закрылась. Человек улыбнулся: охота становилась интересной. Беккер здесь… Я чувствую, что .
Попрыгунчик был любимым детищем коммандера, смелой попыткой изменить мир. Увы, как и большинство других поисков божества, она закончилась распятием. - Хорошо, - сказала. - Я немного погорячилась. - Немного? - Глаза Бринкерхоффа сузились.
