More importantly, for the vast majority of dimensions, the nanobricks have over 88% co-polarized power transmission efficiency, which could be attributed to the low reflection and nearly no absorption of the dielectric metasurface at the telecommunication wavelength.
Further, this scheme has resulted in a significant enhancement (more than 80%) of p-polarized output power as compared to placing a polarizer in the resonator.
This scheme resulted in an enhancement of p-polarized output power of more than 80% as compared to the p-polarized output power without birefringence compensation.
We report a study on the enhancement of linearly p-polarized output power in long pulse (2 20 ms) multimode operation of single rod Nd YAG laser.
In order to avoid that the XPD evaluation is shadowed by the poor antenna XPI for some line of sight (LoS) Rx locations, a proper time gating has been therefore applied to the impulsive responses to remove the LoS contribution from the co- and cross-polarized received power values.
The main contribution of this paper is the proposed method of soil moisture estimation using a low-cost GPS L1 receiver, a horizontally polarized antenna, and power spectrum analysis.
A p-polarized average output power of 215 W has been achieved with a slope efficiency of 4.5%, which is on higher side for a typical long pulse single rod Nd YAG laser system.
The ADS-based receiver model is composed of the six-port model constructed on the measurement results of the RWG 90° hybrid coupler, two pairs of cross-polarized antennas, four power detectors, low-noise amplifiers (LNAs), millimeter-wave amplifiers A2, and baseband amplifiers A3 (gains of 5 dB, 25 dB, and 30 dB, resp).
Using this geometry, a maximum linearly p-polarized average output power of 415 W and a pulse energy of 150 J was achieved with a slope efficiency of 4.3%, which is on higher side for typical lamp pumped long pulse Nd YAG lasers.
Spain is polarized: on one hand power lies in the Army, which is opposed to liberalization; on the other disaffection with the regime, particularly on the part of industrial workers, continues to seethe.
