Abstract With the development and wide applications of wireless communication technology, limited spectrum resources fixed allocation policy could no longer satisfy demand for communication. Just this reason, many become holes because they are allocated but not used. Cognitive radio is now becoming one most important techniques high utility these holes. If available to cognitive users abundant ...

This study describes the development to date of a computational full-body human phantom based on the VHP female dataset. Its unique feature is full compatibility both with MATLAB and specialized FEM computational software packages such as ANSYS HFSS/Maxwell 3D. Applications for low-frequency and radio-frequency electromagnetic modeling are

Laser ranging systems are a widely used form of electronic system and generally influenced by complex electromagnetic environments. We laser comprising the VL53L0X sensor module as research object designed sensitive experimental platform based on system. In this work, we have shown that interference signals can affect performance systems. The signal was found to enter through chip selection por...

The purpose of this research is to present efficient models of novel materials and surfaces based on metamaterials (MTM) and/or electromagnetic band-gap structures (EBG) suitable for large scale simulation in electromagnetic compatibility (EMC) problems. It is shown that the employment of digital filter (DF) techniques provides an efficient means of describing such materials (which inevitably c...

An analytic model is proposed to estimate the electromagnetic field transmission line coupling for both radiated emission and immunity using TEM cell measurements. Further, a coupling impedance is introduced to determine the domination between electric and magnetic fields of the fieldline coupling. Comparison of measurement and calculation results confirms the accuracy of the model. The model a...
