Herein Zinc phthalocyanine (ZnPc) based multifunctional devices are fabricated and characterized. The device fabrication included formation of an Au nanosheets onto n-Si wafers and coating these nanosheets with 500 nm thick ZnPc layer. Silver and platinum were used to form a Schottky and an ohmic contacts with n-Si and ZnPc, respectively. The device hybrid structure (Ag/n-Si/Au/p-ZnPc/Pt; abbreviated as ASZ) is composed of Ag/n-Si Schottky arm and p- and n- layers forming pn junction separated by Au nanosheets. Electrical and photoelectrical measurements on the ASZ devices have shown their ability to perform as conventional metal-oxide-semiconductor capacitors (CMOS). These CMOS devices showed light and frequency controlled charge accumulation, depletion and inversion mechanisms within the range of 1.0-50 MHz. The flat band and threshold voltages of the ASZ capacitors are engineered by the imposed ac signal frequency and by infrared (IR) light. In addition, ASZ devices performed as biasing controlled IR photosensors and as current rectifiers. A rectification ratio of 103, IR light sensitivity of 39, specific detectivity of .96×109 Jones and current responsivity exceeding 9.0 mA/W are recorded at biasing voltage of 4.5 V. Moreover ASZ devices displayed microwave resonator characteristics presented by negative capacitance effect, resonance –antiresonance phenomena and high microwave cutoff frequency. The latter is larger than 10 GHz nominating the device for 6G technology applications.

“…The user rate constraint is expressed in equation (23f) , and

represents the user's minimum rate requirement. The analog beam selection constraints, expressed in equations (23g) , (23h) [ 76 , 77 ], state that each user may select only one analog beam, that an analog beam may correspond to any number of users, and that users who select the same analog beam are grouped together into a single NOMA user cluster [ [78] , [79] , [80] ]. The analog beam selection variable is discrete in the optimization problem (23a) , (23b) , (23c) , (23d) , (23e) , (23f) , (23g) , (23h) , the SIC decoding sequence variable is a combination variable, and the power allocation and IRS phase shift variables are continuous.…”

“…Since the rotating permanent magnet can be equivalent to two orthogonally placed magnetic dipoles, the magnetic feld of RMBMA in the three-layer medium can be synthesized by the magnetic feld of two orthogonal magnetic dipoles in the three-layer medium. In the cylindrical coordinate system, the total feld is written as the sum of the transverse electric feld and the transverse magnetic feld [17][18][19][20], and the boundary conditions are satisfed on the interface. Te magnetic feld of the horizontal magnetic dipole in the three-layer medium is shown in formula (2), where c z is the z-direction wave number in seawater and c r is the radial wave number.…”

Aiming at the application requirements of underwater cross-domain communication, based on the equivalent relationship between the rotating permanent magnet and the orthogonal time-varying current loop, this paper establishes an air-seawater-seabed three-layer medium model and analyzes the magnetic field distribution and propagation characteristics of the rotating permanent magnet-based mechanical antenna (RMBMA). Based on the electromagnetic field simulation software FEKO, the influence of vertical rotation and horizontal rotation of RMBMA on the radiation magnetic field is analyzed. The magnetic field distribution and magnetic field attenuation characteristics of RMBMA at different depths are obtained by simulation. The influence of RMBMA operating frequency and magnetic moment on the propagation characteristics is studied. The research shows that the horizontal rotation of the magnetic source is better than the vertical rotation in the long-distance underwater communication. When the magnetic source and the receiving point are close to the interface of the medium, the magnetic field strength and the propagation distance can be relatively increased. With appropriate frequency and magnetic moment, the magnetic field strength and communication distance can be further increased.
