“…Since an ASRA is an oscillator, it exhibits the well-known phenomenon of injection synchronisation in which case the instantaneous frequency of the ASRA follows that of the forcing signal provided the difference of frequency between them lies within a specified range called the locking range [21,22]. Over the locking band ASRA exhibits (i) the phenomenon of FM-AM conversion, (ii) discrimination against interfering tones or unwanted disturbances and (iii) square law current voltage characteristics.…”

“…This papers looks into the possibility of monolithic behaviour of an active slot-ring antenna that is manifesting transmission, reception, and demodulation at the same time [16][17][18][19][20][21][22]. Specially, these papers demonstrate that (1) an active microstrip slotring antenna can act as a tracking demodulator while it is receives with excellent noise squelching capability, and (2) it can act as an aid to the development of a software defined discriminator which can adapt to different radio environment.…”

A Gunn mounted active microstrip slot-ring antenna (ASRA) has been investigated for the reception of FM microwave signal. Current well/valley phenomenon has been successfully utilized to demodulate the modulation information. The monolithic behaviour of an active slot-ring antenna as a lock-in amplifier, FM (Frequency Modulation) to AM (Amplitude Modulation) converter and square law detector has been demonstrated in this paper. Theoretical analysis coupled with experimental results has been presented. The proposed receiving scheme is unique in the sense that it does not require IF electronics for the purpose of demodulation. It also works well in a multi-channel environment due to the excellent noise-squelching property of an Injection Locked Gunn Oscillator.

“…And ultimately, it is imagined that the poles are frozen on the imaginary axis like the case of an ideal linear harmonic oscillator so that the oscillation neither grows nor decays. Many researchers have done detailed study on the laser-induced microwave oscillator (Eliyahu and Maleki 2003;Biswas, Chatterjee, and Pal 2012). But, they are silent about the pole movement of this type of oscillator.…”

An RLC circuit with poles on the left half of the complex frequency plane is capable of executing transient oscillations. During this period, energy conversion from potential to kinetic and from kinetic to potential continuously goes on, until the stored energy is lost in dissipation through the resistance. On the other hand, in an electronic or optoelectronic oscillator with an embedded RLC circuit, the poles are forcibly placed on the right-half plane (RHP) and as far as practicable away from the imaginary axis in order to help the growth of oscillation as quickly as possible. And ultimately, it is imagined that, like the case of an ideal linear harmonic oscillator, the poles are frozen on the imaginary axis so that the oscillation neither grows nor decays. The authors feel that this act of holding the poles right on the imaginary axis is a theoretical conjecture in a soft or hard self-excited oscillator. In this article, a detailed discussion on pole movement in an electronic and opto-electronic oscillator is carried out from the basic concept. A new analytical method for estimating the time-dependent part of the pole is introduced here.
