Any frequency at which electromagnetic radiation is useful for telecommunication. Note: in this publication the terms RF and microwave are interchangeable and refer to the frequency range 300 HZ-300 GHz.
the frequency in the portion of the electromagnetic spectrum that is commonly used to carry information over distances via radio waves. It typically encompasses the AM radio band (0.54 -1.7 MHz) to high microwave frequencies (100s of GHz) but may extend beyond these somewhat arbitrary limits.
An electrical current that alternates the poles in the radiofrequency range (300 kHz–36 Hz); the high frequency current used in electrosurgery.
Form of energy composed of electromagnetic waves that are converted into heat used in the Closure type of saphenous vein ablation.
Data after being converted from ultrasound to electrical signals, but before being processed, are in the RF range of electromechanical energy. Analysis of RF signals may give rise to tissue characterization in IVUS.
The portion of the electromagnetic spectrum in which electromagnetic waves can be generated by alternating current.
radiation used in MRI whose waves are in the frequency range of 300 MHz to 3 kHz.
is a form of energy that is used to ablate, or destroy, tissue. It is used to treat serious arrhythmias.
