In subject area: Engineering Piezoelectricity is a phenomenon of electric polarization on the opposite faces of asymmetric crystals resulting from the application of an external mechanical stress. From: Medicine in Novel Technology and Devices, 2023 ...
Polarization decomposition by a birefringent plate is studied in Fig. 1.5. Experiments indicate that photodetectors PDx and PDy are never triggered simultaneously, meaning that an entire photon reaches either PDx or PDy (a photon never splits). Therefore, the corresponding probabilities that photodetecto...
Interpreting the meaning of translation When a complex radar target is illuminated by linearly or circularly polarized energy, the reflected signal is, in general, elliptically polarized. In orde... A Chesterman - 《Teaching Education》 被引量: 16发表: 2006年 Modeling Nonlinear Propagation of Optic...

All above have significant illumining and directing meaning for exploiting polarimetric measurements capability of current radar equipments and enhancing their information acquisition and processing capacity. 展开 关键词: Magnitude sum-and-difference polarization pattern interference cancellation spatial virtual ...
Microwave radiation is emitted from a narrow-band horn antenna and is collimated using a parabolic mirror into a , 300 mm diameter beam which illuminates the sample with an approximate plane wave at close to normal incidence (h , 3u). The same mirror refocuses the reflected beam to the ...
Moreover, this polarization sensitivity depends on the direction of the incoming light, meaning that when light is directed in one direction the array produces binary images such as QR codes, while in the other direction it can reproduce grayscale photographs. This opens exciting possibilities for ...
The wireless repeater system550is comprised of a receiver system552, a receiver system554, a transmitter system556, and a transmitter system558. The meaning of the term “repeater” varies, but in the context of the invention, the term “repeater” means a system that receives, amplifies, and...
In an example, a/2=b=6 mm, Lc=27 mm, g=0.5 mm and fop=30 GHz. The resulting BW based on (15) is 6 GHz. In the embodiments described above, the OMT 14 forms a planar structure, meaning that it has a uniform thickness over its entire width and length. In the illustrated embodi...
The complexity of polarization structure in mono-pulse antenna is proved firstly. It is verified to be sensitivity to the polarization of target returns. Based on the polarization characteristics of sum-and-difference channel in mono-pulse radar, the PSM of target can be measured by signal ...
