Lab Session (1)

Supervisor: Dr. Hany Hammad TAs: Yasmine Abdalla Randa El Khosht Effat El-Khashab

Course Title

“A Look at some of the Advances/Practices

in the Wireless Communication Systems from an Electromagnetic Point of View”

Course Objective

Course Contents

• Design of RF passive circuits using Electromagnetic CAD

tools

• Active Microwave Circuit Design

• Prototyping and Measurements

Modern Simulation Tools

CST (Computer Simulation Tool)

Microwave Studio (CST)

• EM field simulation software

• Simplifies solving complex structure as it solves Maxwell’s

equations numerically inside the structure

• gives a complete insight about the E & H-fields behaviors within

the structure in either time or frequency domain

• Enables prediction of designed circuit response before going into

the complicated and costly process of fabrication

Microwave Studio Solver

Microwave Studio has 4 different solvers:

1) Transient Domain Solver.

2) Frequency Domain Solver.

3) Eigen Mode Solver.

4) Integral Equation Solver.
