Ocean waves are powerful forces of nature that can vary dramatically in size and danger. This video explores just how dangerous ocean waves can get by comparing different types of waves from ...

They offer pass-band and stop-band (band-gap) to electromagnetic waves in the same way as the semiconductor do in electronics. Another important characteristic of these materials is the ability to ...

Researchers demonstrated that specific electromagnetic wave frequencies can disrupt the SARS-CoV-2 Spike protein structure in virus-like particles, leading to reduced infectivity in cell models ...

Estimating patient radiation dose The term ‘radiation dose’ can refer to one of several measures (table 1). Dose area product (DAP) is used in X-ray and fluoroscopic imaging (eg, invasive coronary ...

Table 2 shows the comparison of the -20 dB cut-off frequencies and bandwidths of the different dual band EBGs. From the comparison, it can be concluded that cutting a slot shifts the band towards the ...

How common is electromagnetic hypersensitivity? In general, researchers have found that around 1.5% to 5% of the population believe they are a sensitive or “allergic” to electromagnetic fields.

For more than 15 years, a group of scientists in Texas have been hard at work creating smaller and smaller devices to "see" through barriers using medium-frequency electromagnetic waves — and ...

If the wavelength of this electromagnetic wave is very long (greater than 10 meters), we call it a radio wave. For shorter waves, in the range of 1 millimeter to 1 meter, that would be a microwave ...
