Generation of High-Frequency Oscillations by Electromagnetic Shock Wave at Its Synchronism with Backward Harmonic of Periodic Transmission Line Based on Multilayer Heterostructure

The present paper deals with the possibility of generation of high-frequency oscillations by electromagnetic shock wave traveling in synchronism with backward spacial harmonics (group velocity is opposite to the phase velocity) along the previously suggested quasi-periodic microstrip transmission line with capacitance cross links based on multilayer heterostructure (exhibiting hysteretic C(V) characteristic) 1-4]. Just as at synchronism with the direct harmonics, in the case of backward wave synchronism a direct transformation of a short videopulse into a radiopulse (100 GHz, 5-10 V) is possible. However the generated radiopulse here can be significantly longer.
