IXR is essentially the Jones matrix condition expressed as a cross-polarization ratio, and as such it is a measure of how numerically stable the true polarization can be recovered from measured antenna voltages. Also, as it is simply related the Jones condition number, it is numerically easy ...

In this work, log-periodic antennas with improved cross-polarization level were studied. It was found that some modifications of the traditional design lead to an essential improvement of the co-to-cross polarization ratio up to 40 dB. An improved design of a log-periodic dipole antenna with ...
The implemented antenna achieves an average a gain of 9 dBi, a cross-polarization ratio of 29 dB, an isolation of 35 dB within LTE band. The out-of-band suppression level is more than 40 dB within the 2G and 3G frequency bands from 1.71�C2.17 GHz. It can be used as the antenna...
Co-polar component of E1 = E11 and cross-polar component of E1 = E12 XPD = 20 log (E11/E12) Polarization Isolation (極化隔離度): The second measure is polarization isolation (I) that is defined by the ratio of received co-polar power to received cross-polar power and thus takes into...
Cross Polarization is a technique in solid-state NMR that exploits the dipolar interaction between dilute and abundant nuclei to observe dilute nuclei, overcoming sensitivity and signal-to-noise ratio issues. It involves transferring magnetization between nuclei by satisfying the Hartmann–Hahn condition ...
The gain, cross polarization ratio, and front to back radiation ratio of the proposed antenna are found to be higher than that of a conventional broad wall longitudinal slot array antenna. An equivalent circuit of triple band antenna is also presented. © 2016 Wiley Periodicals, Inc. Microwave...

It is found that values of the degree of cross-polarization in uniaxial crystals fluctuate more rapidly with larger deviation of correlation length parameters (δij –δii), but show slight variation with larger ratio of refractive index (ne/n0) or incident beam wavelength. Results also show ...
