1. 1. Investigation of Hybrid Simulation Methods for Evaluation of EMF Exposure in Close Proximity of 5G Millimeter-Wave Base Stations

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : David Anguiano Sanjurjo; [2020]
   Keywords : 5G; base station; EMF exposure; hybrid simulation method; millimeter wave;

   Abstract : With the emergence of Fifth Generation (5G) mobile networks, the employment ofhigher frequencies in the millimeter-wave (mmWave) range and the realization of agreat number of beams in 5G radio base stations (RBS) make the electromagnetic (EM)simulation of RBS products very costly in terms of hardware and time requirements.In order to compute the electromagnetic field (EMF) exposure in close proximity of theRBS, more efficient simulation methods are required.

3. 2. Investigation of Near-Field Contribution in SBR for Installed Antenna Performance

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Harald Hultin; [2019]
   Keywords : Shooting and Bouncing Rays; Geometrical Optics GO ; Physical Optics PO ; antenna modeling; computational electromagnetics CEM ; CST; dipole; ray tubes; Geometrisk Optik; Fysikalisk Optik; antennmodellering; elektromagnetism; CST; dipol;

   Abstract : To investigate near-eld contributions for installed antennas, an in-house code iswritten to incorporate near-eld terms in Shooting and Bouncing Rays (SBR). SBRis a method where rays are launched toward an object and scatter using GeometricalOptics (GO). These rays induce currents on the object, from which the totalscattered eld can be found. READ MORE
