  1. Standing waves Coupler 800-1200 MHz Isolated port Excited port ELECTROMAGNETIC 3DSOLVER • 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

  2. ELECTROMAGNETIC 3DSOLVER • 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 • 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

  3. ELECTROMAGNETIC 3DSOLVER • 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...

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

  15. ELECTROMAGNETIC 3DSOLVER AWR Microwave Office using EM3DS as electromagnetic engine

  16. 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

  17. 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

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