Description |
Despite the efforts of specialists in the manufacture of generating units, all such devices until now generate not only the useful signal, but also higher order propagation modes [2]. To reduce power level of higher order propagation modes usually use filters [1], but their disadvantage is the high cost and complexity. The issue of determination of higher order propagation modes spectrum are devoted such fundamental works as [4] (Fig. 1) and [3] Tabl 1. Fig. 1 shows the relationship between higher order propagation modes for a waveguide section 90x45mm. Table 1 shows the quantitative estimation of the spectrum, which will be used in the simulation. Interest in this subject is not weakened, and so far [5] since for great variety of practical applications this problem has great importance. For example, in the process of drying and heating operations, especially practical value has the ability to measure the power of wave types, which will allow to create a uniform distribution of power flux density of the heated object by adjusting the intencity the individual types of waves. In our view this area is sufficiently investigated, but metrological direction is remained little studied. Meanwhile, there is the prospect of more accurate measurements, in particular, the microwave passing power multiprobe method, which led to interest in this important topic. The physical and mathematical and metrological model of higher order propagation modes in multiprobe microwave multimeter with three sensors was composed. The higher order propagation modes error estimation, which is proposed, minimizes error by shifting sensors from the middle of the waveguide broad wall to the periphery, without changing the distance between the sensors along the direction of energy propagation through the waveguide. |
