In this paper, based on the ATM method variable mass particles in the quantummechanics of free potential transmittance the complex reflection potentialbiochemical sensors and phase modulation oscillating field theory analysis of theproblem.Introduction to papers on supersymmetric quantum mechanics theory briefintroduction. Next comes how to establish any potential function of theone-dimensional transfer matrix. Any potential function of the one-dimensionalinfinite divided into a series of thin layers, when the width of the thin layer tends toinfinity, can be used to replace the use of constant potential potential function in eachthin layer, this series of step potential and the potential function. Then the wavefunction in the form of the sum of the exponential form said thin layer, and then withthe continuous nature of the derivative, you can get the transfer matrix of the wavefunction. And is derived by calculating the equation of ATM phase.ATM-based method, we study the transmittance of the freedom ofone-dimensional potential field (V (x)0) variable mass distribution of the particles.Use point canonical transformation method, we know the type of the variable massdistribution of particles equivalent potential field and its transmission spectrumclosely related. Equivalent potential for the potential well, at the level of the intrinsictransmittance reaches a maximum. The barrier, if the the particles incident energy isless than the potential barrier height, the transmittance rate is very small, once theparticle energy greater than the barrier height, the transmission rate of the shock in thevicinity of1.Reflected potential use of discontinuous several functions to construct thesuperpotential obtained by analyzing the reflection potential is incorrect. This articlepoints out the complex reflection potential use of complex superpotential to constructand test the robustness of the potential use of this method.Quantum mechanics and classical mechanics, there are some very peculiarphysical phenomena. Wherein the particles in attracting potential reflections (or areflection phenomenon at the turning point) is called the quantum reflection, we know that even if the energy higher than the potential barrier in quantum mechanics, theparticles have a certain probability its penetration, a phenomenon known as quantumtransmission. In recent years, ultracold atoms atomic hologram and atomic mirror hasbeen a lot of attention of the people, has a transmission nano-electronic devices havegradually been developed, but for the experiment, we can not make a good theoreticalexplanation. Not absorb any of the one-dimensional potential function of particles inthe study, obtained through the use of particle reflectance and transmittance formulaATM method Sub-waves reflected the real reason for the formation of quantumreflection.In this paper, through biochemical sensors, Symmetrical Metal-CladWaveguide SMCW oscillating field, using phase modulation method to modulate thesensor and the feasibility of the theoretical analysis. Through the Mach-Zehnderinterferometer experiment Improvement, and then come to a phase modulation of theexperimental apparatus.: Phase modulation method having higher sensitivitycompared with the light intensity and having a greater range of variation in therefractive index derived by theoretical analysis and calculation.
