Electromagnetic bandgap (EBG) structures are periodic arrangements of dielectric and metallic elements engineered to prohibit the propagation of electromagnetic waves over specific frequency bands. In ...

When it comes to actual antennas in the real world, much of our knowledge is empirical. We know very broadly theories that explain how a point charge radiates (Maxwell’s equations), the need for ...

Antennas are a key component to any RF gadget. But antennas often only perform well over a narrow band of frequencies. For some applications, this is acceptable, but often you would like to ...

A research team co-led by a scientist at City University of Hong Kong (CityU) has developed a novel antenna that allows manipulation of the direction, frequency and amplitude of the radiated beam, and ...

Over the past few decades, the explosive proliferation of smartphones, Wi-Fi, and Internet-of-Things (IoT) devices has intensified the need for additional frequency resources. The traditionally used ...

Antennas receive and transmit electromagnetic waves, delivering information to our radios, televisions, cellphones and more. Researchers in the McKelvey School of Engineering at Washington University ...

Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...

Scientists have hypothesized for over six decades the possibility of observing a form of wave reflections known as temporal, or time, reflections. Researchers detail a breakthrough experiment in which ...
