transfer matrix method (tmm) has been applied to analyze characteristics of semiconductor laser optical amplifiers. the input signal is sinusoidal modulating wave and we do not assume the modulating bias signal as well. we have shown that the distoration arises from gain modulation at low modulation frequencies, but in microwave modulation frequencies, the gain takes an average value and the re...

Microwave photonics can be generally defined as the study of high-speed photonic devices operating at microwave or millimeter wave frequencies and their use in microwave or photonic systems. In this multidisciplinary field at the interface between microwave techniques, ultra fast electronics and photonic technologies, typical investigations include, for example, high-speed and microwave signal ...

At the present time, the research programs of the Environmental Biophysics Branch cover essentially two areas-nonionizing radiation (microwaves) and noise (auditory and nonauditory effects). Two new programs-the biological effects of light and molecular biophysics-will be started in the very near future. It is the aim of scientists working in the microwave program to develop new microwave expos...

The IEICE (Institute of Electronics, Information and Communication Engineers) Transactions on Electronics announces a forthcoming special section on "Microwave and Millimeter-Wave Technology" to be published in October 2016. With the recent and rapid growth of wireless applications (5G, WLAN, WPT system, millimeter-wave radar, sensor), there are increasing demands of high performance/small size...

Our approach is to observe both acoustic and microwave backscattering from wind-roughened water surfaces in wind wave tanks, and to model the surface in a manner that will explain both types of scattering. The acoustic and microwave systems used are fully coherent so that Doppler spectra as well as backscattering cross sections can be obtained. Our wave tank arrangements are designed so that th...
