The design of novel spiral antenna with extended legs is a good solution for high absorption rate at low absorption frequency of 2.52 THz.
Spiral antenna, with extended legs, is a good solution for high absorption rate at low absorption frequency and can be used as electrode lead simultaneously for simplified manufacturing process.
The design of spiral-type antenna with two separate linear antennas or two connected linear antennas on the bridge legs, shown in Fig. 1d, e, is a good solution for high absorption rate at low absorption frequency of 2.52 THz when the rotation angle is set to 360*n (n = 1.6).
The calibration of the iron concentration was done by using standard iron solutions for atomic absorption purchased from Fluka.
The amine gradient process might be one of solutions for light absorption problem of photoresist for the next generation lithography.
The stabilised nanoparticles were finally suspended in toluene to form stable, high-optical-quality colloidal solutions for optical absorption and fluorescence studies.
From each sample, 13.75 µl was taken and diluted to 100 µl forming 250 ppm solutions for which absorption spectra were measured from 200 800 nm.
This value was high compared to that for the commercial X-ray contrast agent with the same iodine concentration as the Au concentration, which indicated that the Au/SiO2 particle colloid solutions were sensitive for absorption of X-ray.
Based on these results, pH 7.0 of sample solutions was selected for absorption in the following tests.
An approximate solution for the simultaneous absorption and reaction of two gases in a liquid has been presented based on the film theory, assuming a nonlinear (exponential) profile for the concentration of each of the gaseous species in the film.
