In this paper, a new analytical approach has been presented for solving strongly nonlinear oscillator problems. Iteration perturbation method leads us to high accurate solution. Two different high nonlinear examples are also presented to show the application and accuracy of the presented method. The results are compared with analytical methods and with the numerical solution using Runge-Kutta m...

in this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave rof) system that uses a dual drive mach zehnder modulator (dd-mzm), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. the input to the dd-mzm are binary phase shift keying (bpsk), quadrature phase shift keying (qpsk), 8-phase shift keying (8-psk) and...

In this article, we are dealing with a model consisting of a classical Van der Pol oscillator coupled gyroscopically to a linear oscillator. The major problem is analyzed. The regular dynamics of the system is considered using analytical methods. In this case, we provide an approximate solution for this system using parameter-expansion method. Also, we find approximate values for frequencies of...
