One other important issue to be noticed in the design to provide
omnidirectional (or low gain variation) is that the slots should have not only physical circular symmetry on the circular waveguide but also the fields on the slots should have circular symmetry.
The horizontal slot is cut onto all metal walls to provide vertically polarized
omnidirectional radiation pattern.
3] is tuned not only for
omnidirectional radiation pattern, but also for the leaky characteristic.
Thomas, "A dielectric
omnidirectional reflector," Science, Vol.
From Figure 5 which represents the transmission spectra of PC1, PC2 and PC3 under grazing angles for the TM polarization, we see that each of the three considered bands exhibit an
omnidirectional reflection and they overlap each other at different angles.
Third, to control variability among subjects due to differences between their previous hearing aids and the experimental devices, we chose subjects who were previous users of output-compression,
omnidirectional hearing aids.
As I researched it, I found that I was Far from the first person to see it this way; and that both theory and practice of
omnidirectional drive had been developed.
The interconnecting,
omnidirectional pore structure of MEDPOR Biomaterial allows integration with the patient's tissues by allowing fibrovascular in-growth.
Trian is bringing in an amazingly full line of ELAC products, from economical home theater speaker packages to high-end systems with the company's interesting 4Pi
omnidirectional ribbon tweeter and resonance-free pleated foil JET tweeter.
Three models are included in the MS700I Series: The MS700I offers an
omnidirectional scan pattern designed for medium to high volume retail, documentation and coupon processing.
They provide high-intelligibility voice reproduction and high-intensity visual alert stimuli for emergency alarm and protective signaling, and they can deliver up to 118 dB of
omnidirectional sound.
a manufacturer of laser and holographic bar code scanners, has announced that DaimlerChrysler has increased the number of Metrologic HoloTrak IS8500
omnidirectional bar code scanners in use at its assembly plant entrance and exit gates.
