Docket #:2009-05

This Proposal has been approved, and is now a Milestone Nomination

This is a draft proposal, that has not yet been submitted. To submit this proposal, click on "Edit with form", check the "Submit this proposal for review" box at the bottom, and save the page.

Is the achievement you are proposing more than 25 years old?

Is the achievement you are proposing within IEEE’s fields of interest? (e.g. “the theory and practice of electrical, electronics, communications and computer engineering, as well as computer science, the allied branches of engineering and the related arts and sciences” – from the IEEE Constitution)

Did the achievement provide a meaningful benefit for humanity?

Was it of at least regional importance?

Has an IEEE Organizational Unit agreed to pay for the milestone plaque(s)?

Has an IEEE Organizational Unit agreed to arrange the dedication ceremony?

Has the IEEE Section in which the milestone is located agreed to take responsibility for the plaque after it is dedicated?

Has the owner of the site agreed to have it designated as an Electrical Engineering Milestone? Yes

Year or range of years in which the achievement occurred:


Title of the proposed milestone:

First Millimeter-wave Communication Experiments by J.C. Bose, 1894-96

Plaque citation summarizing the achievement and its significance:

In what IEEE section(s) does it reside?

IEEE Calcutta Section

IEEE Organizational Unit(s) which have agreed to sponsor the Milestone:

IEEE Organizational Unit(s) paying for milestone plaque(s):

IEEE Organizational Unit(s) arranging the dedication ceremony:

IEEE section(s) monitoring the plaque(s):

Milestone proposer(s):

Please note: your email address and contact information will be masked on the website for privacy reasons. Only IEEE History Center Staff will be able to view the email address.

Street address(es) and GPS coordinates of the intended milestone plaque site(s):

Calcutta, India

Describe briefly the intended site(s) of the milestone plaque(s). The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.

Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need.

The Presidency college Calcutta (now Kolkata), India, where he developed,invented tested the Millimeter wave communication system or his residence where he had worked mostly, now converted to BOSE INSTITUTE

Are the original buildings extant?


Details of the plaque mounting:

How is the site protected/secured, and in what ways is it accessible to the public?

Both are Government Academic and ResearchInstitutions. In the Bose Institute all his works are preserved.

Who is the present owner of the site(s)?

Government/Scientific Research Organization

A letter in English, or with English translation, from the site owner(s) giving permission to place IEEE milestone plaque on the property:

A letter or email from the appropriate Section Chair supporting the Milestone application:

What is the historical significance of the work (its technological, scientific, or social importance)?

In 1895, Jagadis Chunder Bose first demonstrated here in Calcutta (now Kolkata), India, transmission and reception of electromagnetic waves at 60 GHz over a distance of 23 meters through two intervening walls by remotely ringing a bell and detonating some gunpowder. For his communication system, Bose pioneered development of a host of millimeter-wave components that included: spark transmitter, coherer, dielectric lens, polarizer, horn antenna and cylindrical diffraction grating.

What obstacles (technical, political, geographic) needed to be overcome?

The reason for the choice of millimeter wave by Sir J.C. Bose was primarily due to the advantage of studies of quasioptical properties of the radio waves within his laboratory of limited size, that was available to him at the Presidency College. However, the components and systems developed by Sir J.C. Bose, initially at millimeter wave and subsequently at microwave, were outstanding discoveries made more than 100 years ago, in Calcutta, India, most of which are now being utilised, in a modernised form for Earth/space links and remote sensing

What features set this work apart from similar achievements?

For his communication system, Bose pioneered development of a host of millimeter-wave components that included: spark transmitter, coherer, dielectric lens, polarizer, horn antenna and cylindrical diffraction grating.Bose chose quasi optical Millimeter wave frequency range.The wavelengths he used ranged from 2.5 cm to 5 mm.
