  2. Microwave burn - Wikipedia

    en.wikipedia.org/wiki/Microwave_burn

    Microwave burns are burn injuries caused by thermal effects of microwave radiation absorbed in a living organism.. In comparison with radiation burns caused by ionizing radiation, where the dominant mechanism of tissue damage is internal cell damage caused by free radicals, the type of burn caused by microwave radiation is by heat—health effects colloquially associated with the term ...

  3. EmDrive - Wikipedia

    en.wikipedia.org/wiki/EmDrive

    When power flows into the EmDrive, the engine warms up. This also causes the fastening elements on the scale to warp, causing the scale to move to a new zero point. We were able to prevent that in an improved structure. Our measurements refute all EmDrive claims by at least 3 orders of magnitude.

  4. Electromagnetic radiation and health - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation...

    The field strength of electromagnetic radiation is measured in volts per meter (V/m). [2]: 139. The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States. [3][4] In 2011, the World Health Organization (WHO) and the International Agency for ...

  5. Bioelectromagnetics - Wikipedia

    en.wikipedia.org/wiki/Bioelectromagnetics

    Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...

  6. Medical applications of radio frequency - Wikipedia

    en.wikipedia.org/wiki/Medical_applications_of...

    RF diathermy is a medical treatment that uses RF induced heat as a form of physical therapy and in surgical procedures. It is commonly used for muscle relaxation. It is also a method of heating tissue electromagnetically for therapeutic purposes in medicine. Diathermy is used in physical therapy to deliver moderate heat directly to pathologic ...

  7. Microwave auditory effect - Wikipedia

    en.wikipedia.org/wiki/Microwave_auditory_effect

    The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of the human perception of sounds induced by pulsed or modulated radio frequencies. The perceived sounds are generated directly inside the human head without the need of any receiving electronic device. The effect was first reported by persons ...

  8. Electromagnetic shielding - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_shielding

    In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials. It is typically applied to enclosures, for isolating electrical devices from their surroundings, and to cables to isolate wires from the environment ...

  9. Microwave transmission - Wikipedia

    en.wikipedia.org/wiki/Microwave_transmission

    Microwave transmission is the transmission of information by electromagnetic waves with wavelengths in the microwave frequency range of 300 MHz to 300 GHz (1 m - 1 mm wavelength) of the electromagnetic spectrum. Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of ...
