EM.Tempo Tutorial Lessons
EM.Tempo Tutorial Lesson 1
Title:
Analyzing a Center-Fed Resonant Dipole Antenna
What you will learn:
This tutorial guides you through all the necessary steps to set up and perform a basic FDTD simulation and visualize and graph the simulation results. Specifically, you will use the wire dipole wizard to create the geometry of a resonant half-wave dipole antenna in the project workspace. You will examine the port definition observable for computing S/Z/Y parameters. You will also define far-field radiation pattern and near-field sensor observables.
EM.Tempo Tutorial Lesson 2
Title:
Analyzing Scattering from A Sphere
What you will learn:
In this tutorial you will learn to draw spherical objects from the ground up. You will define material groups of different types, will set up a plane wave source to excite your physical structure and define field sensor and radar cross section (RCS) observables for your target
EM.Tempo Tutorial Lesson 3
Title:
Modeling a Probe-Fed Microstrip Patch Antenna
What you will learn:
In this tutorial you will use a wizard to build and analyze a probe-fed rectangular patch antenna on a finite-sized conductor-backed dielectric substrate. You will also learn how to use variables and run a parametric sweep simulation.
EM.Tempo Tutorial Lesson 4
Title:
Modeling a Patch Antenna Array
What you will learn:
A patch antenna array is typically made up of 𝑁𝑥 ×𝑁𝑦 individual patch antennas (radiating elements) arranged on a rectangular grid with a uniform spacing of 𝑆𝑥 and 𝑆𝑦 along the X and Y directions, respectively. In EM.Tempo, you can model patch antenna arrays in a number of different ways:
- Analyze a single isolated patch antenna and use an array factor for radiation pattern calculation. But this method ignores all the inter-element coupling effects.
- Analyze an infinite periodic patch structure and use an array factor for radiation pattern calculation. This method accounts for the interelement coupling effects, but it cannot capture edge and corner effects.
- Construct a finite-sized 𝑁𝑥 ×𝑁𝑦 patch array on a finite-sized substrate. This is a full-wave treatment of the antenna array structure but it may prove computationally very expensive.
In this tutorial you will try out the third method from the above list and model finite-sized probe-fed patch array structure.
EM.Tempo Tutorial Lesson 5
Title:
Analyzing a Planar Microstrip Band-Stop Filter
What you will learn:
In this tutorial you will model a two-port planar filter that is excited by two independent sources. You will first use a wizard to create a basic two-port microstrip through line. Then, you will add additional microstrip segments to complete your filter construction.
EM.Tempo Tutorial Lesson 6
Title:
Modeling Rectangular Waveguide Structures
What you will learn:
In this tutorial first you will analyze a two-port rectangular hollow waveguide and examine its TE10 modal fields. Then you will add a number of metallic irises to the waveguide and will turn it into a bandpass filter.
EM.Tempo Tutorial Lesson 7
Title:
Designing a Pyramidal Horn Antenna
What you will learn:
In this tutorial you will build pyramidal horn antennas with different geometrical properties and aspect ratios and will analyze their radiation properties. You will also learn to use EM.Cube’s Python command line and will write you own Python scripts to perform some mathematical calculations.
EM.Tempo Tutorial Lesson 8
Title:
Analyzing a Periodic Frequency Selective Surface
What you will learn:
In this tutorial you will learn how to define periodic structures in EM.Tempo, excite them using plane wave sources and compute the reflection and transmission characteristics of the periodic surface. You will become familiar with the subtleties of modeling oblique incident angles.
EM.Tempo Tutorial Lesson 9
Title:
Modeling Coplanar Waveguide Structures and Lumped Devices
What you will learn:
In this tutorial you will learn how to construct coplanar waveguide (CPW) transmission line structures with different termination types. You will learn about lumped devices like linear resistors and nonlinear diodes. You will examine temporal waveforms of different types for exciting your CPW structure and will investigate the transient response of your circuit. You will also learn how to parameterize geometric objects using independent and dependent variables.
EM.Tempo Tutorial Lesson 10
Title:
Modeling Wave Propagation in Dispersive Media
What you will learn:
In this tutorial you will learn how to use Gaussian beam sources to illuminate non-dispersive and dispersive material blocks. You will also generate a fixed-cell mesh for your project and set up time-domain animation of the fields propagating inside the material blocks. In the first part of the tutorial lesson, you will consider a non-dispersive dielectric material. In the second part, you will work with a left-handed metamaterial and will explore the effect of a doubly negative refractive index on the beam propagation.
EM.Tempo Tutorial Lesson 11
Title:
Simulating a Monopole Antenna Interacting with a Human Head Model
What you will learn:
In this tutorial you will learn how to import several external CAD models, transfer them to EM.Tempo and combine them with your own object drawings. You will construct a physical structure with different types of materials, especially a lossy dielectric. You will use a new type of mesh generator for discretization of this structure.
