Title: Hermann B Sequeira: Innovator in Microwave and Millimeter Wave Technologies
Introduction
Hermann B Sequeira is a notable inventor based in Baltimore, MD, with a significant contribution to the field of microwave and millimeter wave technologies. He holds a total of 8 patents, showcasing his innovative spirit and technical expertise. His work has advanced the understanding and application of calibration methods and dielectric structures in various technological domains.
Latest Patents
Among his latest patents is a calibration method for apparatus evaluating microwave/millimeter wave. This calibration procedure for vector network analyzers utilizes a known standard, an unknown standard, and a pair of offsets bearing a known length ratio (2:1) between them. Measurements taken on the standards and their combinations with the offsets result in self-verifying redundant equations that furnish error terms according to well-known flow graph models, the reflection of the unknown standard, the transmission factor of the waveguiding medium, and a figure of merit for the quality of the acquired raw data without the necessity for computing the error terms.
Another significant patent involves dielectric slab transitions and power couplers. This invention comprises a multi-layer dielectric slab structure that allows single mode propagation over a relatively wide frequency band. The design reduces radiation losses due to coupling of the desired mode to the substrate modes and the conductors, making the structure relatively insensitive to small deviations from parallelism among the different interfaces.
