Abstract:
Martens (1984) proposed a high efficient and simple formed DFT algorithm-RCFA,, whose efficiency can be compared with that of WFTA or that of PFA, and whose structure is similar to that of FFT. The authors have proved that, in the case of radix 2, th...

Abstract:
This paper presents a new edge detector using 5x5 window, which can reduce the noise effect efficiently but not increase the width of the detected edge which always happened,, in case of using 5x5 window edge detector. Besides that, in order to handl...

Abstract:
Starting from the relativistic motion equation and the energy equation of the electron, a large-signal theory which describes the beam-wave interaction of the gyro-peniotron for arbitrary TEmn mode and arbitrary harmonic of the cyclotron frequency is...

Abstract:
A new approach to the EM scattering problem of an inhomogeneous lossy dielectric body is proposed. It is shown that the entire interier electric field distribution can be obtained from the measured exterier field distribution by simple recurrence rel...
