Modeling of a terahertz bandpass filter based on magnetic fluids
In this paper, a bandpass filter model is proposed, consisting of a geometric model of a cuvette with a magnetic fluid on which the Navier - Stokes hydrodynamics equations, the convective transport equation for the level function and the Maxwell system of equations are superimposed. Using numerical simulation, the properties of periodic filamentous structures in a magnetic fluid located in an external homogeneous magnetic field are investigated, depending on the value of the external magnetic field and the parameters of magnetic fluids. Calculations of the transformation of spectral characteristics of broadband THz radiation passing through the formed periodic structures are carried out.
