## 5. CONCLUSION New extraction formulas for noise-wave sources in the noiseequivalent circuit of MESFET and HEMT devices are proposed. The correlation between noise sources is included by defining the complex equivalent temperature, called the correlation temperature. The noise-wave parameters are
CONCLUSION ## Ε½ This study has shown that a discontinuity the tee-junction in . this example behaves as a source in the array, and it can significantly decrease the sidelobe level if its position is well chosen. This shows that exact knowledge of its behavior is essential. In this case, the radiati
This paper presents the application of the nonuniform orthogonal mesh FDTD method combined with Mur's second-order ABC to structures that ha¨e symmetrical planes. Particularly, it is re¨ealed that, in order to combine Mur's second-order ABC with a symmetrical plane, an alternate form of Mur's second
Figure 6 Nonlinearity of PZT Figure 7 Hysteresis of PZT actuator which was controlled by a DrA converter. Many experiments have been done to test the PZT. A typical sample PZT is made of 30 pieces, and its radius is 10 mm. The curves of nonlinearity and hysteresis are shown in Figures 6 and 7. Its n
means of three numerical examples, the functional showed better agreement with the reference results than the traditional scheme, in which the feeding point impedance is computed directly from the ratio of the feeding point voltage and current. Variational-based methods offer a new and more accurate
