• Low radar profile end-fire arrays. Photo.
• Array fed multibeam antenna (MBA) systems.
• Filters (waveguide).
• Dichroic (frequency selective) plates.
• Mode couplers.

Optim Microwave has fabricated:

• 38 dBi, 38 GHz, low profile (3.5 inches), low sidelobe 12 inch reflector antenna. Drawing. Measured patterns; H-plane: 38.6, 39.3, and 40.0 GHz, E-plane: 38.6, 39.3, and 40.0 GHz. This antenna was a first effort prototype designed to meet the FCC category A sidelobe specifications.
• Dichroic plates.
• Microwave multimode couplers for evaluating higher order modes of TWTAs.
• High efficiency feeds and coherent combiners for DSP terminals. Photo.
• S-band tracking feeds for the Air Force ARIA program. Photo.

Optim Microwave has provided:

• Antenna radiation and radio wave propagation studies for cellular communication systems and for warehouse inventory systems.
• Analysis of tracking errors introduced by radomes on airborne satellite tracking platforms.
• Synthesis and analysis of antenna architectures for contractors involved in military communication satellite programs such as MILSTAR, DSCS III, and SDI.

Optim Microwave has developed a suite of computer programs which involve rigorous electromagnetic analysis:

• General two-dimensional method of moments (MOM) code. Used for a variety of applications including antenna and waveguide component design.
• Circular symmetry MOM code. Used for the design of reflector feeds. Provides very accurate model of complex feed systems allowing for multi-mode and multi-band designs. Rigorously includes effects of matching circuitry, radomes, and currents on the exterior surfaces of the feed.
• Rectangular waveguide slot analysis MOM code. Accurately models array effects, finite plate thicknesses, wide slots, and multiple layers of components. Used for the design of slotted waveguide arrays and various waveguide components.
• Physical optics reflector code. Used in the design of reflector systems.
• Generalized 3-D lens code. Used to analyze and design a large class of lens problems, including Luneburg lenses.
• Optimizers. Various optimizers have been written which use the codes above as analytical engines. These optimizers facilitate efficient device design.

Optim Microwave has done work for:

• TRW (Redondo Beach, CA).
• Datron/Transco (Simi, CA).
• Electromagnetic Sciences (Norcross, GA).
• Hughes Research Laboratories (Malibu, CA).
• Microwave dB (Newbury Park, CA).
• U.S. Air Force.
• And many others.
