The networks have harmful effects on people who suffer from the heart diseases, they cause electromagnetic pollution, when people use the cell phones to make the calls, the signals are transmitted back and forth to the base station. Cellular phones The RF waves produced at the base ...
of electromagnetic waves, it has become a hot area of research to develop perfect absorbers based on polarisation independence and incident angle independence, at a range of frequencies from microwave to optical ones. The amazing performance, flexibility, and tunability of these metamaterials will be ...
First, notice the sunset/sunrise colors in the photo. Notice how close to the horizon the moon and sun are. This simply wasn’t possible on April 8. The eclipse began at sea southwest of Mexico, so there would’ve been no land from which to shoot a sunrise shot. Likewise, the eclip...
