In the fifth generation of wireless communication systems (5G), millimeter wave (mmWave) signal can be affected by many challenges in irregular environments such as dust and sand storms. this paper, we investigate attenuation that faces a mmWave link dusty environment for different sizes particles. Further, derive model to calculate total mobile and/or internet things (IoT) base stations highne...

We consider a hydrodynamic model of quantum dusty plasma. prove mathematically that the resulting dust ion-acoustic plasma waves present property being conservative on average. Furthermore, we test this numerically, confirming its validity. Using standard techniques from study dynamical systems, as, for example, Lyapunov characteristic exponents, investigate chaotic dynamics and show numericall...

The numerous idealizations that are involved in the exact microscopic statistical description of complex (dusty) plasmas discussed detail. two prevailing approaches Klimontovich dusty reviewed a pedagogical manner. continuous phase space approximation is introduced, within which more rigorous treatment should collapse to heuristic treatment. plasma equations shown be identical, but there marked...

Dust particles immersed within a plasma environment, such as those in protostellar clouds, planetary rings or cometary environments, will acquire an electric charge. If the ratio of the inter-particle potential energy to the average kinetic energy is high enough the particles will form either a “liquid” structure with short-range ordering or a crystalline structure with long range ordering. Man...

We report on analytical and simulat n studies of mi ophy processes that trigger phase transitions in a dusty plasma subject to ion streaming. For res below the critica ure Pc for condensation, the grains acquire a large random kinetic energy and form a we upled fluid. P is increased to greater than Pc, the grains lose their kinetic energy and reach a strongly coupled crystal e state. The ust he...
