To perform the measurement, we will use our test antenna as the source. Then we will use a linearly polarized antenna (typically ahalf-wave dipole antenna) as the receive antenna. The linearly polarized receive antenna will be rotated, and the received power recorded as a function of the an...
Based on reflection arrangement, two antenna polarization measurement techniques, the absolute polarization measurement method and the polarization‐transfer measurement method are presented with experimental results. In the absolute polarization measurement method or the system calibration, the polarization ...

all possible numbers (1 → ∞/−∞ → −1). In particular, the PR values at the polarity-transition point could approach infinity. Such a polarity transition hereby transcends the conventional PR–diattenuation relationship. Furthermore, our device allows the subtle measurement of pola...
The current needed to maintain a specific voltage shift (typically 10 mV) is directly related to the corrosion on the surface of the electrode in the solution. By measuring the current, a corrosion rate can be derived. The advantage of the LPR monitoring technique is that the measurement of ...
Circular polarization is then achieved whatever the polarization of the elements of the array. Moreover, due to the circular geometry of the array, the entire far field pattern of the array can be obtained with the measurement or the simulation of only one antenna inside the array. The ...
