About E x H

Based in State College, PA, E x H is creating advanced electromagnetics software and design solutions. The founders began the business in 2012 with an interest in a more intelligent approach to computational electromagnetics and optimization-based design. We primarily provide software to analyze and design engineered materials for antennas and optical applications, as well as provide engineering design services for custom antennas. Our software products are based on the sophisticated modeling and design synthesis tools that have been developed by the Pennsylvania State University's Computational Electromagnetics and Antennas Research Laboratory (PSU CEARL).

Why E x H?

The Poynting vector S = E x H, defined by the cross-product of the coupled Electric and Magnetic field vectors, is the direction of energy propagation in an electromagnetic wave. Invented by John Henry Poynting and published in 1884, it has since become a fundamental concept for physics, electromagnetics, and optics. The name is one of the rare coincidences of science by matching so well with its standard interpretation: the Poynting vector may be envisioned as the ray that points in the direction that the light is travelling with magnitude proportional to the power in the wave.

We chose the Poynting vector for our name as a representation of our focus on the core principles of electromagnetics and the success that that yields as new designs and implementation strategies are derived. The vector cross product indicates direction as we pursue our total focus on engineering excellence in every aspect of our business. The Electric and Magnetic fields, coupled through Maxwell's equations, interact to form complex behaviors from a core principles; at E x H, we focus on fundamentals of quality, speed, and utility to produce complex and sophisticated capabilities.

Our Team

Jeremiah P. Turpin, Ph.D
Co-founder and Board Member

Dr. Turpin received his M.S. in Electrical Engineering from the Pennsylvania State University in 2011 and his Ph.D. degree in 2014. In his graduate studies, he studied the application of metamaterials, metasurfaces, frequency selective surfaces, and transformation optics to solutions of practical design problems in the field of electromagnetics. His development of a ray tracing solver for arbitrary 3D gradient-index lenses is the base of E x H's reTORT software. As one of the founders of E x H, Jeremiah brings over a decade of software development experience as well as his knowledge in electromagnetics and stochastic optimizations. With Clinton, he also participated in the Techcelerator program for entrepreneurial development in 2012 sponsored by Ben Franklin Transformation Services and Penn State.


Clinton P. Scarborough, Ph.D
Co-founder and Board Member

Dr. Scarborough received his M.S. in Electrical Engineering from the Pennsylvania State University in 2011 and his Ph.D. degree in 2014. In his graduate studies, he developed techniques and methodologies for the design of advanced metamaterial-enabled, tunable, and reconfigurable antennas. By leveraging new analytical and design approaches, including high-impedance surfaces, dispersion-engineered metasurfaces, and metamaterial-inspired miniaturized antennas, Clinton's innovative antenna designs have improved the state-of-the-art in several categories of communication systems. As one of the founders of E x H, Clinton's design experience is invaluable for the success of the antenna prototyping and consulting wing of the E x H business. With Jeremiah, he also participated in the Techcelerator program for entrepreneurial development in 2012 sponsored by Ben Franklin Transformation Services and Penn State.


Douglas H. Werner
Co-founder and CTO

Prof. Werner has extensive experience in applied computational electromagnetics with an emphasis on the modeling/design of antennas (including conformal, low-profile, miniaturized, multiband, broadband, RFID tag, e-textile and wearable antennas as well as nanoantennas) and phased arrays (including ultra-wideband arrays). In addition, he has made notable contributions in the areas of frequency selective surfaces, electromagnetic absorbers, metamaterials, and transformation electromagnetics/optics devices for a variety of RF, THz, IR and visible wavelength applications. He is a recognized authority on nature-inspired global optimization techniques (e.g. genetic algorithms, particle swarm, clonal selection, covariance matrix adaptation evolutionary strategy, etc.) and their application to solving complex electromagnetic design problems. He has also supervised the design, fabrication and testing of metamaterial-enabled antennas for a wide range of applications.
