Leaky-Wave Antennas (LWAs) enable directive and scannable radiation patterns, which are highly desirable attributes at terahertz, infrared and optical frequencies. However, a LWA is generally ...

Comprising 85 models in 5 different categories, Pasternack’s line of millimeter-wave waveguide antennas offers operating frequencies from 40 GHz to 220 GHz for use in R&D, military, aerospace, ...

Engineers have invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas. They built photonic integrated devices that had ...

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 ...

IRVINE, CALIF.—Pasternack Enterprises released a new family of high frequency, WR-15 waveguide antennas designed for high-bandwidth applications including point-to-point links, GigE wireless LAN, ...

This is a preview. Log in through your library . Abstract The problem of Lamb wave propagation in an axially multi-layered waveguide is treated by a multi-modal approach. A general formalism is ...

As discussed in the last tutorial, there are three important parameters to determining the impedance of a coax line, whether it’s flexible RG-59, helix or rigid coax: the ratio of the inner and outer ...
