“…According to the degree of correlation in R X , the order of correlation degree of ideological and political quality under the quality-oriented education of college students in eight universities can be determined as follows. The model evaluation indicator system is determined according to the analytic hierarchy process [10] and the 1-9 scale method [11,12] proposed by Sati, so as to establish the integration matrix ðX − 1Þ [13,14]. Finally, a comprehensive evaluation is conducted on indicators at all levels.…”

The current model for evaluating ideological and political education is mostly based on a weighted evaluation of related educational parameters, like the structure of the school and the structure of the teachers. In this cycle, the impact of college students’ general development on the construction of their ideological and political education is not considered, which makes evaluations less exact by and large. To work on the exactness of the evaluation model, you ought to upgrade the construction of the evaluation model, with the quality of education for college students as the center advancement. Education quality evaluation calculation and model parameter output calculation are integrated. In terms of the quality of training for college students, simulation tests reveal that the proposed model has the lowest blunder esteem and the highest general evaluation precision. This makes it easier to decide what kind of ideological and political education is best.

In this paper, a compact six-channel optical demultiplexer and coupler have been designed using a novel photonic crystal resonator for Intermediate Frequency Over Fiber (IFoF) in Fifth Generation (5G) networks. The demultiplexer and coupler differ from the existing work with the introduction of defected pentagon and trapezium structured resonator and its positioning in the IFoF enabled 5G heterogeneous fiber wireless network. Point defects and displacement of photonic crystal rods have been introduced in these resonators and the structure of the waveguide is altered to exhibit the demultiplexer and coupler design. The proposed demultiplexer operates in S and C band and the coupler functions in C and L band. The footprint of the demultiplexer and coupler is found to be 270 µm 2 . The minimum and maximum quality factor of the demultiplexer is found to be 1823 and 3422, respectively. The maximum and minimum cross-talk of the demultiplexer using pentagon resonator is found to be −10 and −34 dB, respectively.

The paper illustrates a photonic crystal micro ring resonator based pressure sensor utilizing the variation of refractive index of the material and the structural deformation. FEM is employed for reformed structure analysis. Structural deformation and change in refractive index are taken as input variables in FDTD simulation and the external pressure is measured by analyzing shift in resonance wavelength. A comparative study of the rod type and the hole type photonic crystal micro ring resonator based pressure sensor is reported in this paper. Both the structures are ultra compact and can be used for compact photonic integrated circuits.dynamic range, FDTD, FEM, micro ring resonator, photonic crystal, pressure sensor | INTRODUCTIONPhotonic crystals (PhC) are artificially created periodic microstructure of two dielectric materials of different refractive indices (RI). This type of periodic arrangement creates a photonic band gap (PBG) through which electromagnetic waves of a range of particular wavelength are restricted to propagate. 1 The wide constitutional specifications range in the PhC provides the flexibility to control the properties of PhC based devices. [2][3][4][5] Thus the manipulation of the electromagnetic waves is possible in the PhC based devices by the use of different dielectric materials and by varying the geometrical parameters like the lattice distance of crystal structure and the radius of the rods of the PhCs. This unique property of the PhCs has opened up a new window in the area of photonic sensors. PhC based structures have numerous applications in the designing of logic and arithmetic operations. Recently M. Mohammadi et al. published an article on the design and simulation of a half adder based on grapheme ring resonators. The output spectrum of the model was analyzed using Finite-difference-timedomain (FDTD) and coupled-mode theory (CMT) method. 6 PhC based cascaded ring resonator structures are also used by different researchers to design different multiplexer and demultiplexer circuits. [7][8][9] Among the two approaches, used for the sensing purposes based on PhC namely the intensity variation and the spectrum analysis, the later one is usually preferred because of its higher sensitivity. 10 Recently, new fields of research Uttara Biswas, Bhuvneshwer Suthar, Deepak Kumar, and Chittaranjan Nayak contributed equally to this work.
