When the threshold value for the axial ratio of circularly
is generally considered as 3 dB, the designed antenna can be said to provide good circular polarization performance over the full azimuth plane and 65 degrees beamwidth in the elevation plane both for simulation and measurement results.
In this paper, two designs of dual-band dual-sense circularly
polarized slot antenna are proposed based on a construction of concentric deformed annular slots with a stepped microstrip feed line.
The concept of a bidirectional circularly
polarized array with the same sense at both axial ends was theoretically and experimentally investigated in this paper.

polarized arrays composed of linearly polarized elements," Electronics Letters, Vol.
The variations of the attenuation of right-hand circularly
polarized electromagnetic wave in unmagnetized and magnetized plasma along with the plasma density under fixed plasma collision frequency are obtained based on the physical model and theoretical analysis, which is depicted in Figure 2, where the electromagnetic wave frequency f is 2.

Polarized Aperture-Coupled Stacked Microstrip Antenna For Global Positioning Satellite.
I used XFdtd to separate the resulting RF fields in the sphere into the part that was circularly
polarized in the same direction as the nuclear precession ([B.
5" panel with circularly
polarized filters and anti-reflective treatment is under $100 in OEM quantities.
In the test condition for each study, subjects were exposed to a circularly
polarized, 60-Hz sinusoidal magnetic field generated at a resultant flux density of 28.
Amorphous, randomly oriented polymer films, can be aligned using a linearly polarized laser, and the orientation can be destroyed by a circularly
polarized laser, thus creating a reversible optical storage process in a millisecond time frame.
The wood block is advanced to the face of the disc in a manner such that its long grain direction can be controlled at various angles with respect to the path of the circularly
travelling teeth and thereby changing the nature of the resulting fibrous elements.
It is demonstrated that circularly
polarized radiation induces fermion resonance without the use of a permanent magnet, a technique that we name radiatively induced fermion resonance (RFR).
They found high levels of circularly
polarized light in a region of the Great Nebula in the constellation of Orion, a star birthplace 1,500 light years away.
Cohen not only knocks down a straw man, then, she makes no mention of th on-going theoretical debates about the nature of ethnicity, and, at one point, even defines ethnic identity circularly
as "a sense of connection with one's ethnic group.
, the "male"--first the male member, then the hand--is altered into its opposite gender, then back again: The hand, usually acting as female organ, here masculinely "feminizes" the male organ and then is explicitly associated with the female.
