The manuscript deals with the assessment of Radio over Fiber (RoF) system including pure electrical baseband, pure radio frequency band centered around 60 GHz, and hybrid radiooptical system at the same RF band using a global simulation. In this work we focus on RoF solution to improve the low coverage of the 60 GHz channel caused by high free-space attenuation. A realistic co-simulation of the Wireless...
The use of Constant False Alarm Coded Anticollision Radar (CFACAR) is very interesting in automotive environment. Due to the orthogonality properties of used codes this system is most robust to multi-user interferences. The actual version of the receiver called in this paper Single Correlation Receiver (SCR), is not able to detect the targets in very low input Signal to Noise Ratio (SNR). To resolve...
A new 3D time-domain physical numerical electromagnetic/transport modeling has been used to investigate the photoswitch (PS) operation. It is mainly based on a self-consistent solution of both the Maxwell and drift-diffusion equations by means of the FDTD method. The model has been applied to a GaAs microstrip line photoswitch. Some results illustrate the model capabilities. Some circuit functional...
In this work we present a microwaves circuit electromagnetic simulator. It is fundamentally based on the 3D self-consistent numerical solution of the Maxwell's equations and the macroscopic conservation equations derived from the transport equation of Boltzmann. It can include linear electrical elements. As an illustration, it is applied to the simulation of a microstrip transmission line and the...
