in order to achieve coherent detection heterodyne receivers at supra-thz frequencies are under development by integrating in a single waveguide cavity a schottky based mixers fed by a quantum cascade laser (qcl) as local oscillator (lo).Thanks to the qcl enough lo power is available to drive the mixer.Currently a simple combination of passive thermal and electrical bias control is proposed for the frequency stabilization of the qcl.

For each of the cases reported in Table 3, Table 4 and Table 5 show the comparison among the numerical results obtained by the full-wave analysis ([f.sub.FW], [Q.sub.FW]) [8], our empirical model ([f.sub.re], [Q.sub.re]) and the classical theory of the metallic waveguide cavity ([f.sub.rc], [Q.sub.rc]) [17].
Since the axes of the vibrators and slot lie in {x0y} plane, interaction between the vibrators and the slot over the waveguide cavity is absent (Figure 1).
A computer model was set up to study the filling process in the waveguide cavity during through-thickness embossing.
The existing Boundary Contour Mode Matching (BCMM) method for the computation of integrated waveguide cavity structures with inherent milling radii has been extended.
In Figure 5, it can be pointed out that, as the side length of the substrate square [W.sub.s] increases, the resonant frequency decreases due to the increase of the square waveguide cavity. In Figure 6, it is shown that the resonant frequency increases with the increase of the slot square width [W.sub.c].
