Coupling is the ratio of the power measured at the output port relative to that measured at the forward coupled port. Directivity is the ratio of the power measured at the reverse coupled port ...

New research by Edith Cowan University (ECU) and Fiona Stanley Hospital aims to decrease noise levels in intensive care units ...

For several decades the microwave community contemplated the idea of constructing antennas that beat the diffraction limit for directivity. In fact as early in 1922, Oseen, with reference to ...

As the directivity of a soundwave depends on the size of the source and its frequency, a directed beam can practically only be achieved with ultrasound. Even though we are not able to perceive ...

Audiomaster Technologie provided 70 AKG iX8-o outdoor loudspeakers, with 36 speakers fitted to lighting poles along the 421m ...

Premier audio manufacturer Klipsch has announced not one but two new powered speakers: the Klipsch R-40PM and the Klipsch R-50PM. Being powered speakers, both models integrate amplification ...

The transmission line model, combined with the measured and computed thermal plots, suggest a model for the computation of radiation patterns of a rectangular microstrip patch antenna in the TM 01 ...

You also get a Klipsch one-inch aluminum LTS tweeter and 90 x 90 square Tractrix Horn that provides impressive coverage, ...
