In this study, two versions of circularly
polarized omnidirectional antennas, which can be used in satellite communication systems of telemetry and telecommand antennas, are designed and demonstrated.
The geometry of proposed dual-band dual-sense circularly
polarized Antenna-1 and Antenna-2 are shown in Fig.

The variations of the attenuation of right-hand circularly
polarized electromagnetic wave in plasma along with the magnetic induction of external magnetic field and the plasma density under fixed plasma collision frequency are obtained based on the physical model and theoretical analysis, which is depicted in Figure 3, where the electromagnetic wave frequency f = 2.
Polarized Microstrip Antenna For GPS Application.
Upon simulating the same situation with XFdtd, we found that neither the circularly
polarized magnetic field component rotating with nuclear precession ([B.
To produce the circularly
polarized field, one axis of the field was phase-shifted 90 [degrees] with respect to the other axis.
Finally, some of the newest results indicate the possibility to induce chirality in nonchiral liquid crystalline azobenzene polymers, even in the absence of any structural chiral center, simply by irradiating with appropriate circularly
In conventional ESR and NMR, the resonance is detected by a circularly
polarized radio or microwave frequency beam, and the energy states of the electron and proton are separated by a very tiny amount by using a very powerful permanent magnet, usually an expensive superconducting magnet.
In the 1930s scientists discovered that circularly
polarized light can destroy molecules of a particular handedness depending on its polarity.
Each model features an audible horn, circularly
polarized antennas, and mounting hardware for such options as a light stack, electronic eye presence detector, and wireless LAN communications.
