Radio Frequency Protection
Techniques Division


This division of Titan's Advanced Technologies Group (formerly Jaycor), is based in Santa Barbara, CA, and is involved in a wide range of electromagnetic (EM) protection activities ranging from major multi-year programs for the Defense Special Weapons Agency (DSWA) to small EMI consulting activities.

One major DSWA program involves developing and validating coupling models and protection techniques for systems exposed to high power microwave (HPM) sources. Coupling models for narrowband backdoor coupling are incorporated into a Windows®-based computer code called JEM RF. The code flows a user specified EM environment through a system to generate bounds on coupled pin stresses. The stresses are compared with levels required for damage, upset, and interference across the specified frequency band.

Another DSWA program is concerned with developing and quickly transferring to end users, innovative protection techniques for all electromagnetic effects, hostile and non-hostile, natural and manmade. Emphasis is on hostile EM effects such as EMP, HPM, and other emerging EM weapons. Jaycor, now Titan, and its and subcontractors on this program, Boeing, Stanford Telecom, Teledyne Brown Engineering, and Lindgren provide a broad source of advanced technology and the experience needed to apply it to real-world problems.

A major activity under this program is supporting PM TOC (Program Manager Tactical Operation Centers) in Huntsville. The Titan Team is developing a database of equipment immunity for military and commercial equipment used to assemble TOCs. Immunity will be determined using new test data, taken specifically for this program, standards the equipment is known to have met, or an assessment based on similarity of design to equipment with know immunity levels.

A computer code, JEM TOC, will be used to access the database and estimate the ability of the TOC to meet its mission requirements over the full range of EM environments specified for the system. The equipment immunity database can be used by other programs for a variety of applications.

Other computer products developed by the division include JEM 3D, a powerful three-dimensional finite difference code for solving Maxwell's equations. It is used to solve a wide range of EMP and HPM problems.

The division is also developing the Testable Hardware Workbook, a computer code for satellite survivability engineers. It incorporates an electronic version of the SGEMP test protocol developed by a Jaycor team for DSWA, and integrates it with a tool for "building" a spacecraft and calculating SGEMP effects down to the pin level. It uses models documented in the protocol and automates many of the modeling tasks.
