Expert Microwave Engineering Consulting Services

Microwave Engineering knowledge was instrumental in detecting and understanding the residual microwave energy created with the birth of the Universe 13.7 billion years ago. The microwave signature left by the birth of the Universe illustrates the importance of understanding and solving Microwave Engineering problems to satisfy a plethora of domestic, industrial, scientific, and government applications in the 21st century.

The applications for Microwave Energy continually increase with demand from different market sectors, so this field of engineering has expanded rapidly over the past decade. However, experience with solving Microwave Engineering problems analytically and numerically is extremely important, which is the service provided by SiberSci, LLC. Numerical results must always be questioned to ensure that the model parameters and boundary conditions are properly enforced, so analytical techniques are used to validate the results provided by every numerical simulation. This important step is often overlooked by those inexperienced with solving Microwave Engineering problems, which results in wasted time and money when faulty results are used to fabricate hardware prototypes that do not work. SiberSci, LLC‘s extensive experience prevents this from happening.

SiberSci, LLC is an experienced Microwave Engineering Consultant providing Microwave Engineering Consulting Services for a wide range of circuit topologies. The services provided to clients include theoretical analysis, design, development, fabrication, testing, validation, and optimization of the following abbreviated list of hardware options:

  • transmission lines (microstrip, stripline, coplanar waveguide, coax, rectangular waveguide, cylindrical waveguide, elliptic waveguide,…),
  • filters (lowpass, bandpass, highpass, band reject,…),
  • resonators (coaxial, cylindrical, rectangular, clam-shell, dielectric,…),
  • delay lines,
  • phase shifters,
  • couplers,
  • impedance-matching circuits,
  • dielectric lenses,
  • Signal Integrity (SI) analysis,
  • LDMOS, GaN, SiC, and GaAs power amplifiers, low-noise amplifiers (LNAs), and application-specific amplifiers,
    1. 1Load-Pull Optimization of amplifier active device performance.
  • Temperature stabilized GUNN diode oscillators,
  • RF, microwave, millimeter-wave and THz dielectric characterization of temperature-dependent complex permittivity and permeability of plasmas, powders, liquids, and solids, and
  • systems analysis.

Our experience allows us to review client performance specifications and size constraints for their defined microwave hardware, from which SiberSci, LLC can make recommendations for one or more hardware configurations to satisfy these requirements. SiberSci, LLC can also review proprietary performance specifications, size constraints, and client-proposed hardware configurations to determine if these concepts are suitable for the intended application, or determine if the design concept must be modified to satisfy the stated requirements.

Performance and physical limitations for each design concept are documented during the review process, and modifications to each design concept are documented to illustrate how a design concept must be adapted to satisfy the performance and size limitations. If some portion of the performance or size specification is found to be physically impossible to achieve, then these problem areas are revealed along with recommendations to circumvent these barriers to achieving the requisite performance.

Microwave Engineering Computational ElectroMagnetics (CEM)

Furthermore, SiberSci, LLC is experienced in using Ansys HFSS as part of the Ansys Electronics Workbench, CST Microwave Studio as part of the CST Studio Suite, FEKO, Comsol, SONNET Software, and Keysight ADS, and Genesys to support the Computational ElectroMagnetics (CEM) aspects of these programs. Clients can specify the use of one or more of these CEM tools for their project as long as the client provides a valid license for using the code, or pays for contract access to the code of choice. If the client is unable to select the appropriate CEM code for their project, then SiberSci, LLC is prepared to assist each client with selecting the appropriate CEM codes(s) to ensure the success of their project.

Finally, it is important for each client to realize that the accuracy of CEM simulations is dependent upon the frequency and temperature-dependent material properties (thermal conductivity, complex permittivity, relative permittivity, loss tangent, electrical conductivity, density, specific heat,…) of the metals and dielectrics used for fabricating their circuits, so these material properties must be measured so they can be included in the CEM simulations. Laboratory and contract resources are available to determine these material properties, which are essential for providing accurate CEM simulations of both circuits and systems. SiberSci, LLC provides each client with the capability to only use valid material properties for their CEM simulations.
