Electromagnetic Engineering Consultant for RF, Microwave, Millimeter-Wave and Antenna Design

SiberSci, LLC is an electromagnetic engineering consulting firm that researches, designs, develops, prototypes, optimizes, and helps manufacture hardware in the RF, microwave, and millimeter-wave spectrums. Core service areas are antenna engineering, microwave engineering, millimeter-wave engineering, RF engineering, microwave and RF heating and drying engineering, and RF and microwave safety training. SiberSci also provides failure analysis, reverse engineering, patent support, and expert witness testimony.

SiberSci, LLC was founded by Dr. Scott Best, an electromagnetic engineer whose professional experience spans both industry and government. Prospective clients contact Dr. Best directly to discuss their project requirements.

SiberSci, LLC is based in Owensboro, Kentucky, USA, and is a BBB Accredited Business listed in the IEEE-USA Consultants Database. Projects begin with a phone or email discussion at 270-228-4901 or scott_best@sibersci.com.

SiberSci supports industrial, consumer, medical, avionics, and military applications. Typical clients are companies developing or manufacturing RF and microwave products, industrial heating and drying equipment, plasma systems, communications hardware, and medical devices such as microwave ablation systems.

An electromagnetic engineering consultant is an engineer who uses Maxwell's equations, computer simulation and laboratory measurement to design, test or fix hardware that radiates, guides or absorbs electromagnetic energy. Typical projects include antennas, RF, microwave and millimeter-wave circuits, waveguides, RF and microwave heating systems, and RF exposure safety. SiberSci, LLC covers 1 Hz to 300 GHz and is led by Founder & CTO Dr. Scott Best, Ph.D.

Frequency usually decides. SiberSci's RF engineering covers 1 Hz to 300 MHz, where circuits are much smaller than a wavelength and lumped inductors and capacitors work well. Microwave engineering covers 300 MHz to 30 GHz, where transmission lines, waveguides and distributed circuits take over. Millimeter-wave engineering covers 30 to 300 GHz. Because SiberSci covers all three, a project that crosses a boundary stays with one consultant.

A millimeter-wave engineering consultant designs, simulates and measures circuits, antennas and waveguide components from 30 to 300 GHz, where free-space wavelengths shrink from 10 mm to 1 mm. At these frequencies, a fraction of a millimeter in machining or assembly changes performance. Typical applications include 76–81 GHz automotive radar, 5G FR2, satellite links and imaging. SiberSci's lab measures up to 300 GHz.

Both heat materials with electromagnetic energy, but at different ISM frequencies. RF heating uses 6.78, 13.56, 27.12 or 40.68 MHz with parallel-plate, strayfield or RLC resonator applicators, and its long wavelengths suit large or thick loads. Microwave heating uses 915 MHz, 2.45 GHz, 5.8 GHz or 24.125 GHz in cavities and waveguide applicators, and suits thinner layers and smaller parts. The material's measured dielectric properties decide which works best, and SiberSci designs both.

An RF and microwave safety consultant helps a company keep employees and the public below RF exposure limits. The work includes reviewing transmitters, heaters and waveguide systems for leakage, explaining the FCC limits in 47 CFR 1.1310 and the related OSHA, FDA and state rules, defining exclusion zones, and training staff. SiberSci provides RF and microwave safety training and onsite reviews for teams that work with high-power RF, microwave and heating equipment.

A good antenna engineering consultant can simulate, build and measure an antenna, not only model it, and has worked in your frequency band. SiberSci designs, simulates, builds and measures antennas from 1 MHz to 300 GHz, including RFID, microwave ablation, X-band and 76–81 GHz radar arrays. To get a quote, send the frequency, bandwidth, gain, pattern, polarization, VSWR, size limits and operating environment.

SiberSci designs and optimizes a wide range of antennas, including parabolic reflectors, corner reflectors, Cassegrain and inverse Cassegrain antennas, standard gain horns, corrugated horns, dielectric lenses, Luneburg lenses, Rotman lenses, spiral antennas, patch antennas, near-field and far-field RFID antennas, and application-specific antennas.

SiberSci prices each project individually. Send Dr. Scott Best a detailed description of the work and your schedule, and SiberSci will return a budgetary quotation along with a contract defining the scope of work. Cost depends on technical complexity, required simulation or prototyping, laboratory measurements, and deadline.

A Non-Disclosure Agreement (NDA) is negotiated and signed before any project details are disclosed. The NDA protects your business-sensitive information, intellectual property, and proprietary designs throughout the engagement.

Starting a project takes four steps: (1) contact SiberSci by phone at 270-228-4901 or email at scott_best@sibersci.com; (2) sign an NDA; (3) share a detailed description of the work and your schedule; (4) receive a quotation and contract. Work begins once the contract is in place. Contact SiberSci.

Contact SiberSci anyway. If the project falls outside SiberSci's expertise, Dr. Best will refer you to another electromagnetic engineering consultant who can do the work.

Yes. SiberSci provides free online calculators: a Wavelength and Impedance Calculator, Skin Depth Calculator, Dielectric Heating Calculator, Coax TEM Mode Calculator, Circular Waveguide Calculator, Rectangular Waveguide Calculator, and Rectangular Waveguide TE(m,n) and TM(m,n) mode calculators.

Skin depth is the depth at which current density in a conductor falls to about 37% (1/e) of its surface value, and it shrinks as frequency or conductivity increases. Engineers typically make conductors or plating at least several skin depths thick to minimize loss in transmission lines, cavities, and waveguides. The free SiberSci Skin Depth Calculator computes it for any metal conductivity and frequency.

Dielectric heating power depends on the operating frequency, the material's dielectric loss factor, the electric-field strength inside the material, and the mass, volume, heat capacity, and target temperature rise over a set time. The free SiberSci Dielectric Heating Calculator estimates the average power and electric field required for a defined material volume, mass, and heating time.
