The part of the electromagnetic spectrum with large infrared waves and short radio waves, an oven that cooks food very quickly or made to cook in one of these ovens. An example of microwave is a type of cooking that uses energy waves to cook food; microwave cooking. Microwave signals propagate in straight lines and are affected very little by the troposphere.

High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
