  1. 12 ELECTROMAGNETIC 3DSOLVER A truly Affordable, Efficient, Powerful, Easy to learn Electromagnetic modeling tool Now 64 bit technology

  2. ELECTROMAGNETIC 3DSOLVER 12 • New Features • 64 bit • Enhanced GUI: exploiting Vista and W7 power • Full parametric: now even substrates can have parametric thickness • Parametric analysis: define groups of parameters and perform group simulations • Printing implemented • additional tutorials • FreeEM3DS has now reduced limitations!

  3. A pulse propagating in time along a transmission line ELECTROMAGNETIC 3DSOLVER 12 • Time-Domain tools: • Time-Domain Reflectometry: transient analysis of signals • Animation of currents and fields in time • Custom measurements A pulse reflected back by a short circuit at the end of a transmission line

  4. Standing waves Coupler 800-1200 MHz Isolated port Excited port ELECTROMAGNETIC 3DSOLVER 12 • TOOL OF CHOICE FOR • Teaching: • recommended for Microwave, RF and mmWave (theory and circuit design), Electromagnetic Theory, Electromagnetic compatibility, MEMS design courses, MMIC and IC design course • easy to learn (complete set of animated tutorials), create animations (AVI, GIF) demonstrating basic principles (standing waves and matching, interference, working principles of a component), competitive prices for equipping complete classrooms • keep in touch with one of the most used tools in the Microwave and RF industry • seamlessly interfaced with the most popular microwave & circuit design suite: AWR Microwave Office

  5. ELECTROMAGNETIC 3DSOLVER 12 • TOOL OF CHOICE FOR • Advanced research: • Entirely developed by a research team, includes many unique features (controlled current sources, multimode calibration, ability to enter any frequency dependent parametric expression to describe new materials, interaction with acoustic waves: investigate the impact of material properties (electrical, mechanical), new electromagnetic phenomena and devices, develop your own calibration technique for measurements, time-domain feature • A Pascal Object-Oriented scripting let you handle directly internal parts of EM3DS! Create your own menu in EM3DS, link to events/parameters/results • It is 3D: simulate at the same time dielectric resonators, planar circuits, active linear devices Scripting Acoustic modeling

  6. ELECTROMAGNETIC 3DSOLVER 12 • TOOL OF CHOICE FOR • Design of RF, Microwave, mmWave and MEMS circuits: • Flexible: Parametric definition of objects and materials; you can tune, modify, optimize parameters; extract a parametric macro-model (real-time estimation of response as a parameter is changed); create macro-commands by a pascal script; no grid to fit into... • Very Fast: Asymptotic extraction technique (fast for many frequency calculation), Variational (coarse mesh gives good results as well), SmartFIT selects automatically and adaptively frequencies to catch and plot resonances; uses a Method of Moments: only conductors are meshed (insensitive dramatic cross-sectional aspect-ratio), and complex substrates, including tents of layers, are quick and easy to simulate • Very Powerful: Allows a broad class of devices: microstrip, stripline, coplanar waveguide, coupled strip based components, filters, couplers, planar antennas and array of antennas, dielectric resonators, acoustic resonators, active linear devices (MESFETS, HEMTS), transitions, matching circuits • Complete suite: includes many kind of charts (Smith’s, polar antenna, S/Z/Y/losses/VSWR/Phase difference/Q measurement, contour plot, surface plot of currents/field, far field plot, 3D views etc); a linear circuit simulator to attach sub-circuits, connect lumped elements, manually calibrate etc; a broadband spice model extractor: extract equivalent circuits automatically; import/export results in touchstone format; filters to import/export GDSII and DXF structures...

  7. ELECTROMAGNETIC 3DSOLVER 12 Macro-modeling/tuning: optimize and tune your design!

  17. ELECTROMAGNETIC 3DSOLVER 12 Antenna design (printed Yagi-Uda)

  18. ELECTROMAGNETIC 3DSOLVER 12 Teaming: AWR Microwave Office using EM3DS as electromagnetic engine

  19. ELECTROMAGNETIC 3DSOLVER • EMI test case: coupling between a strip in the PCB and a wire travelling in the larger box. Range 10-50MHz Larger Box Trace in the PCB FR4 Inner Box External wire Not only microwaves: EMI and RF problems

  20. Electromagnetic modeling • Purpose: evaluate the electromagnetic field distribution across “planar” and “quasi-planar” structures when a sinusoidal electrical signal is applied somewhere -the point of excitation is a “port” • What planar means: a structure which is entered layer-by-layer, as common in semi-conductor technology: e.g. microchips, printed circuit boards, microelectromechanical devices

  21. Components • Directional coupler: designed for application in the mobile phone market

  22. If you already have another software package: EM3DS is low cost, so you can check your design by two independent packages, or use the faster for the specific problem If you have not another software package: EM3DS is a fast and accurate tool to work in RF, microwave and antenna engineering You have now also FreeEM3DS, completely free for academy and personal use, with enhanced capabilities Just download it and try it!
