Reference excerpt

Nader Engheta (Persian: نادر انقطاع; born October 8, 1955) is an Iranian-American scientist and professor at the University of Pennsylvania. He has contributed to the fields of metamaterials, transformation optics, plasmonic optics, nanophotonics, graphene photonics, nano-materials, nanoscale optics, nano-antennas and miniaturized antennas, physics and reverse-engineering of polarization vision in nature, bio-inspired optical imaging, fractional paradigm in electrodynamics, and electromagnetics and microwaves.

Background Engheta was born on October 8, 1955 in Tehran. After earning a B.S. degree from the school of engineering (Daneshkadeh-e-Fanni) of the University of Tehran, he left for the United States in the summer of 1978 and earned his Masters and PhD degrees from the California Institute of Technology. He is one of the original scientists in the field of modern metamaterials, and is the originator of the fields of near-zero-index metamaterials, plasmonic cloaking and optical nano circuitry (optical metatronics). His primary work is in metamaterial-based optical nano circuitry, in which properly designed nano structures function as lumped optical circuit elements such as optical capacitors, optical inductors and optical resistors. These are the building blocks for the metatronic circuits operating with light. This concept has been recently verified and realized experimentally by him and his research group at the University of Pennsylvania. This provides a new circuit paradigm for information processing at the nanoscale. His near-zero-index structures exhibit unique properties in light–matter interaction that have provided new possibilities in nanophotonics. His plasmonic cloaking ideas have led to new methods in stealth physics. He and his group have developed several areas and concepts in the fields of metamaterials and plasmonic optics, including, (1) ‘extreme-parameter metamaterials’ and 'epsilon-near-zero (ENZ) metamaterials'; (2) the concept of Omega structures, as one of the building blocks of structured materials,; (3) ultrathin cavities and waveguides, with sizes beyond diffraction limits, providing possibilities for unprecedented miniaturization of devices; (4) supercoupling phenomena between waveguides using low-permittivity ENZ metamaterials,; (5) extended Purcell effects in nano-optics using the ENZ phenomena, in which enhanced photon density of states occurs in a relatively large area with essentially uniform phase; (6) far-field subwavelength imaging lens based on ENZ hyperbolic metamaterials; (7) scattering-cancellation-based plasmonic cloaking and transparency,; (8) merging the field of graphene with the field of metamaterials and plasmonic optics in infrared regime, providing the roadmaps for one-atom-thick optical devices and one-atom-thick information processing,; (9) microwave artificial chirality; (10) “signal-processing” metamaterials and “meta-machine”, and (11) “digital” metamaterials. He has been the H. Nedwill Ramsey Professor at the University of Pennsylvania since January 2005, affiliated with the departments of Electrical and Systems Engineering, Bioengineering, Materials Science and Engineering, and Physics and Astronomy. In 2026, he was elected as a member of the National Academy of Engineering "for contributions to the development of metamaterials and their applications".

Worked examples

Example 1 — a first encounter with Nader Engheta

Start with the simplest possible case. Write down what Nader Engheta claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nader Engheta before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nader Engheta ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nader Engheta

In research: Nader Engheta appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nader Engheta in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nader Engheta is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, 20th-century American engineers, 20th-century Iranian engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Nader Engheta outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
