Abstract :
The transient response of lossy coupled microstrips is studied using the spectral domain approach (SDA) to compute rigorously the dielectric losses. Transient coupling is formulated in the frequency domain using an even/odd mode approach. Results for pulse distortion on a semiconducting substrate are presented showing how losses reduce the signal amplitude without significantly distorting the shape. Distortion due to even/odd mode coupling was the dominant distortion mechanism, while coupling due to differences in the modal attenuation constants had a secondary effect.<>
