Célia M. Q. Ramos,Paulo M. M. Rodriguesl be functions of x, y, ?, ??/?x, and ??/?y. For b. ? 4ac > 0, the equation is hyperbolic and two families of real characteristics exist. As mentioned previously, characteristics are lines across which derivatives of the dependent variables may be discontinuous and along which infinitesimal disturbances may propagate.

Thomas Zwackvoted to the output networks of high-efficiency power ampifiers. The novel type of photonic band-gap structure providing improved characteristics both in the pass and stop bands is proposed. Finally, the fifth-harmonic peaking class F power amplifier design based on the above structure is presented. .
