LENS ANTENNAS - Part 2: Homogeneous lenses: Spherical. | 43/62 | UPV

Título: LENS ANTENNAS - Part 2: Homogeneous lenses: Spherical.


Descripción automática: In this video, the lecturer continues the discussion on lens antennas, specifically focusing on dielectric spherical lenses in the field of technology. The video examines different types of dielectric lenses, which are made from a single material. It covers the shapes of lenses—convex and concave—and the variations such as plano-convex and plano-concave lenses. Special attention is given to how the focal point is determined by the lens's refractive index and shape.

The lecturer goes on to describe simulations that demonstrate how lens antennas can manipulate electromagnetic waves to focus them at a point, or to collimate them into plane waves. They explain how these effects vary depending on the frequency of the waves and show simulations of lenses operating at different frequencies. The discussion includes the directive properties of the antenna and how the wavelength affects directionality.

Finally, the video covers the combination of different lens types—for instance, a concave lens paired with a convex one—demonstrating how these configurations can expand or compress waves. Through simulations, the lecture shows the effect on the wave propagation and how these techniques can be utilized to modify the direction and intensity of waves. This discussion concludes the second part of the lecture series on dielectric lens antennas, specifically addressing spherical lenses.
